Step-by-step explanation:
Is y=1/2x-1 proportional
Answer: No
Step-by-step explanation: Since y=2x+1 does not pass through the origin (i.e. there exists the constant term of 1 ), the variables y and x are not directly proportional - though, they do have a linear relationship.

Solve for x in the equation below.
(x – 2) = –1/4(x – 8)
Answer:
x = 16/5
Step-by-step explanation:
x-2 = - 1/4 (x-8)
4x - 8 = -x + 8
4x +x =8+8
5x = 16
x= 16/5
The solution of the equation is x = [tex]3\frac{1}{5}[/tex].
The correct option is D.
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
Given:
A linear equation,
x-2 = - 1/4 (x-8)
Simplifying,
4x - 8 = -x + 8
4x +x =8+8
5x = 16
x= 16/5
x = [tex]3\frac{1}{5}[/tex]
Therefore, the solution is x = [tex]3\frac{1}{5}[/tex].

Inconsistent System
For a system of equations to have no real solution, the lines of the equations must be parallel to each other.
Consistent System
1. Dependent Consistent System
For a system of the equation to be a Dependent Consistent System, the system must have multiple solutions for which the lines of the equation must be coinciding.
2. Independent Consistent System
For a system of the equation to be an Independent Consistent System, the system must have one unique solution for which the lines of the equation must intersect at a particular.
A.) For the first graph since the lines overlap or lie on each other, therefore, the given system of equation in the first graph will be of Dependent consistent system. Thus, the system will have an infinite number of solutions.
B.) For the second graph since the lines intersect at a particular point, therefore, the given system of equations in the second graph will be an Independent consistent system. Thus, the system will have a unique solution number of solutions. Also, the solution of the equation is the point at which the lines intersect, therefore, the solution of the system of the equation will lie at (-1,2.)
C.) For the third graph since the lines are parallel to each other, therefore, the given system of equations in the third graph will be an Independent consistent system. Thus, the system will have no solutions.

Which ordered pairs are solutions to the inequality y - 3x < -8?
Select each correct answer.
(1, -5)
(-3, - 2)
(0, -9)
(2, -1)
(5, 4)
Answer:
The ordered pairs which are solution to given inequality are:
(0,-9)
(5,4)
Step-by-step explanation:
In order to check if the given ordered pairs are solution of the inequality or not we will put the ordered pairs one by one in the inequality.
If the inequality is holds true for the ordered pair, the ordered pair is the solution.
The inequality is:
[tex]y - 3x < -8[/tex]
So,
For (1,-5):
[tex]y - 3x < -8\\-5-3(1) < -8\\-5-3<-8\\-8<-8[/tex]
(1,-5) is not the solution of given inequality.
For (-3,-2):
[tex]-2 - 3(-3) < -8\\-2+9<-8\\7<-8[/tex]
(-3,-2) is not the solution of given inequality.
For (0,-9):
[tex]y - 3x < -8\\-9-3(0) < -8\\-9 <-8[/tex]
(0,-9) is the solution of the given inequality.
For (2,-1):
[tex]y - 3x < -8[/tex]
[tex]-1 - 3(2) < -8\\-1-3<-8\\-4<-8[/tex]
(2,-1) is not the solution of given inequality
For (5,4):
[tex]y - 3x < -8\\4 - 3(5) < -8\\4-15<-8\\-11<-8[/tex]
(5,4) is the solution of given inequality.
Hence,
The ordered pairs which are solution to given inequality are:
(0,-9)

What is the slope of the line that passes through these two points (8, 4) and (5, 3)?
Answer:
Equation for the slope of the line is, m=y2−y1x2−x1
∵ the point B(5, 8) is above A(3, 4), hence, and B(x2,y2),∵ the point B(5, 8) is above A(3, 4), hence,
A(x1,y1)→A(3,4) and B(x2,y2)→B(5,8)A(x1,y1)→A(3,4) and B(x2,y2)→B(5,8)

The slope is the intensity of inclination thus the slope of the line that passes through points (8, 4) and (5, 3) is 1/3.
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
The slope of a line that passes through (x₁, y₁) and (x₂, y₂) is,
Slope = (y₂ - y₁)/(x₂ - x₁)
Since, the given line is passing through (8, 4) and (5, 3).
Slope = (3 - 4)/(5 - 8)
Slope = -1/-3 = 1/3
Hence "The slope is the intensity of inclination thus the slope of the line that passes through points (8, 4) and (5, 3) is 1/3".

0.2x+2.7x−8.1=6.9+1.1x
The answer is not x = 83 tho
and don't do it for the points
0.2x + 2.7x - 8.1 = 6.9 + 1.1x
Combine like terms on left side:
0.2x + 2.7x = 2.9x
Now you have:
2.9x -8.1 = 6.9 + 1.1x
Subtract 1.1x from both sides:
1.8x - 8.1 = 6.9
Add 8.1 to both sides:
1.8x = 15
Divide both sides by 1.8:
X = 8.3333 ( round as needed) or as a fraction = 8 and 1/3
Answer:
8.3recurring
Explanation:
0.2x+2.7x =2.9x
rewrite the questions
2.9x-8.1=6.9+1.1x
like terms together. Therefore:
2.9x-1.1x = 1.8x
8.1 will go to the other side of the equal sign. Therefore:
8.1+6.9 = 15
Therefore: 1.8x = 15
x =15/1.8 which is equal to 8.3recurring

Answer:
y=3/4x-11
Step-by-step explanation:
When a line is perpendicular to another line, their slope is the opposite reciprocal of that. So in this case, the slope of the perpendicular line would be positive 3/4. Next, plug in the points (8,-5) in the y=mx+b formula along with the new slope. In conclusion, the new point slope formula is y=3/4x-11.
