Graph the following equation: y = -5x + 1
Answer: in your graphplot the point of the y-intercept(which in this case is 1, hence the “+1”)
Step-by-step explanation:
Next 5x is the same as -5/+1 which pretty much means you have to go down 5 times and 1 to the right in a repeated motion until you can no longer plot that point.
then you do the opposite of -5x which is -1/+5 which means you have to go up 5 times and 1 to the left in a repeated motion until you can’t

Answer:
Multiply
Step-by-step explanation:
You need to multiply the number by 10 or 100 or 1000 according to the number. but after multiplying it should become a whole digit. And you also need to multiply 10 or 100 or 1000 in the dividend.

Use the table to work out the values of a , b , c , and d .
Answer:
a = 16, b = 6, c = - 4, d = - 9
Step-by-step explanation:
Substitute the appropriate values of x into the equation and evaluate.
x = - 3 : y = 1 - 5(- 3) = 1 + 15 = 16 → a
x = - 1 : y = 1 - 5(- 1) = 1 + 5 = 6 → b
x = 1 : y = 1 - 5(1) = 1 - 5 = - 4 → c
x = 2 : y = 1 - 5(2) = 1 - 10 = - 9 → d
Answer:
a=16; b=6, c= -4, d= -9
Step-by-step explanation:
[tex]f(x)=1-5x\\f(-3) = 1-5(-3)=1+15=16\\f(-1) = 6\\f(1)=-4\\f(2)=-9[/tex]

1) Through any two points, there is exactly one line.- postulate
2) A line segment is a part of a line and is bounded by two endpoint. - Definition
3) If two lines intersect, then each pair of opposite angles are congruent. - Theorem
What are postulates?"These are statements that are assumed to be true without proof."
What is definition?"It is used to give a precise meaning to a new term."
What is theorem?"It is a statement that can be proved to be true by accepted mathematical operations and arguments"
For given question,
We have been given three statements.
We need to classify them as theorem, postulate and definition.
The first statement is 'Through any two points, there is exactly one line.'
We know that this is the fundamental postulate use in Geometry.
The second statement is 'A line segment is a part of a line and is bounded by two endpoint.'
Above statement is the definition of line segment.
The last statement is 'If two lines intersect, then each pair of opposite angles are congruent.'
We can prove above statement by using Euclid's axiom.
So, above statement is a theorem.
Therefore, 1) Through any two points, there is exactly one line.' - postulate
2) A line segment is a part of a line and is bounded by two endpoint. - Definition
3) If two lines intersect, then each pair of opposite angles are congruent. - Theorem

Find the gradient and y-intercept in this equation:
[tex]8x+2y+9=0[/tex]
Answer:
Gradient: -4
y-intercept: [tex]-\frac{9}{2}[/tex]
Step-by-step explanation:
Step 1 - Subtract 8x from both sides to isolate the 2y + 9
[tex]8x + 2y + 9 = 0\\8x + 2y + 9 - 8x = 0 - 8x\\2y + 9 = -8x\\[/tex]
Step 2 - Subtract 9 from both sides to isolate the 2y:
[tex]2y + 9 = -8x\\2y + 9 - 9 = -8x - 9\\2y = -8x - 9[/tex]
Step 3 - Divide both sides of the equation by 2:
[tex]\frac{2y}{2} = \frac{-8x}{2} - \frac{9}{2}\\y = -4x - \frac{9}{2}[/tex]
In this form, y = mx + b, the m value is the gradient with the b value being the y-intercept. This means:
[tex]y = -4x - \frac{9}{2}\\\\m = -4\\b = -\frac{9}{2} \\\\[/tex]
Resulting in the gradient being -4 and the y-intercept being [tex]-\frac{9}{2}[/tex].

Answer:
( -1,7)
Step-by-step explanation:
{ refer attachment }
Answer:
The answer would be (-1,7)
Step-by-step explanation:
Using the process of elimination we can subtract the two equations to cancel out the y variable. That is subtract the second equation from the first.
3x + y = 4
- 2x + y = 5
x = -1
Now that we have found x we can substitute -1 for x into any equation for y. So, in substituting -1 for x in the second equation we get:
2(-1) + y = 5
-2 + y = 5
y = 5 + 2
y = 7

4 - 3y = 31
Answer:
subtract 4 from both sides
Step-by-step explanation:
you will then get -3y=27 as your equation then you just divide each side by -3 and your answer will be y = -9
Answer:
Step-by-step explanation:
4 - 3y = 31
Step 1: Subtract 4 from both sides
-3y = 31 -4
-3y = 27
Step 2: Divide both sides by (-3)

i think its 2.5 because 15/6= 2.5 so 2.5t=h and the equation is kt=h so 2.5 makes the most sense.

IM DESPERATE FOR AN ANSWER Customers of a phone company can choose between two service plans for long distance calls. The first plan has an $18 monthly fee and charges an additional $0.13 for each minute of calls. The second plan has no monthly fee but charges $0.17 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?
Answer:
450 minutes
Step-by-step explanation:
1st plan
18 + 0.13x = y
2nd plan
0.17x = y
x is minute of calls
y is the total price customers must pay
both of them equal as y = y
y = y
18 + 0.13x = 0.17x
18 = 0.17x - 0.13x
18 = 0.04x
x = 18/0.04
x = 450 minutes
