can someone help me understand how to find the slope intercept form in a equation using ( y=mx+b )please n thank you!
Answers
Answer:
y=-1/2+3
Step-by-step explanation:
first, we have to determine if the slope is positive or negative. if it is going up to the right, it is positive. if it goes up to the left, it is negative. to find the slope, we need two or three points where the x and y values are both whole numbers. for this, we can use the y-intercept (0,3), (-2,4), and (-4,5). we can look at the line and see that from (0,3) to (-2,4) the line rises 1 and runs -2. this supports the claim that the slope is negative. from (-2,4) to (-4,5), the line rises 1 and runs -2. this is the same as the slope from (0,3) to (-2,4), so we can say that it is the slope of the line. since slope is written as rise over run, we can write the slope as -1/2. for the y-intercept, or b, we have to see what y is when x is 0. y is 3, so the y intercept is 3. in y=mx+b, m=slope and b=y intercept, so we plug these values in and we have the graph in slope intercept form.
Answer:
Slope-intercept form: y = - ½x + 3
Step-by-step explanation:
In the slope-intercept form, y= mx + b:
m = slope
b = y-coordinate of the y-intercept, (0, b). The y-intercept is the point on the graph where it crosses the y-axis. At that given point, the value of x = 0.
Start by choosing two points from the graph that you could use to solve for the slope of the line. I often use the y-intercept as one of the points.
Use the following points: (0, 3) and (6, 0):
Let (x₁, y₁) = (0, 3) ⇒ This is the y-intercept.
(x₂, y₂) = (6, 0) ⇒ This is the x-intercept, the point on the graph where it crosses the x-axis.
Substitute these values into the following slope formula:
m = (y₂ - y₁)/(x₂ - x₁)
[tex]m = \frac{0 - 3}{6 - 0} = \frac{-3}{6} = - \frac{1}{2}[/tex]
Hence, the slope of the line is: m = - ½.
As previously mentioned, one of the points we used to solve for the slope is the y-intercept, (0, 3). Its y-coordinate is the value of b = 3 that you will use for the equation.
Therefore, the linear equation in slope-intercept form is: y = - ½x + 3.

Answers
Given info:-
A shop keeper offers a discount of 20% on all the articles at his shop and all makes a profit of 12%.
What is the CP of an article whose MP is Rs. 280 ?
Explanation:-
Given that
The Marked Price of an article (M) = Rs. 280
Discount on it = 20%
Discount (D) = MD/100
⇛ Discount = (280×20)/100
⇛ Discount = 28×2
⇛ Discount =56
Selling Price = Marked Price - Discount
⇛ Selling Price = 280-56
⇛ Selling Price = Rs. 224
Selling Price of the article = 224
Profit on it = 12%
We know that
Cost Price = (100×SP)/(100+g)
⇛ CP = (100×224)/(100+12)
⇛ CP = 22400/112
⇛ CP = 200
Therefore, The CP = Rs. 200
The Cost Price of the article = Rs. 200.
Formula:-
Discount (D) = MD/100M = Marked Price
Selling Price = Marked Price - Discount Cost Price = (100×SP)/(100+g)SP = Selling Price
g = gain or profit

Write an equation for a line parallel to 4x – 2y = 4 that passes through the point (3,22)
Answers
Answer:
y = 2x + 16
Step-by-step explanation:
4x - 2y = 4
-2y = -4x + 4
y = -4/-2x + 4/-2
y = 2x - 2
Slope: 2
Point: (3,22)
y-intercept: 22 - (2)(3) = 22 - 6 = 16
Answer:
y=2x+16 or 2x-y=-16
Step-by-step explanation:
Hi there!
We are given the equation 4x-2y=4, and we want to write an equation for the line parallel to it, that also passes through (3, 22)
First, let's find the slope of the line, as parallel lines have the same slope.
In order to find the slope, we can convert the equation from standard form (ax+by=c) into slope-intercept form (y=mx+b).
Start by subtracting 4x from both sides:
-2y=-4x+4
Divide both sides by -2
y=2x-2
2 is in the place where x is, so the slope of the line is 2
It's also the slope of the line parallel to it.
Writing the equation in slope-intercept form, this is the equation so far:
y=2x+b
Now let's find b
Since the equation passes through the point (3,22), we can use it to help solve for b
Substitute 22 as y and 3 as x:
22=2(3)+b
Multiply
22=6+b
Subtract 6 from both sides
16=b
Substitute 16 as b in the equation.
y=2x+16
We can stop right here, but we can also re-convert it into standard form
To do that, subtract 2x from both sides:
-2x+y=16
There's a rule that the coefficient in front of x CANNOT be negative; in order to change the sign, multiply both sides of the equation by -1
2x-y=-16
Hope this helps!

Answer:b) If there are 20 squares there will be 25 triangles.
c) There are 20 girls
Step-by-step explanation:
b) The ratio here is 4(squares):5(triangles), so if there are 20 squares you have to divide that by the original number of squares, 4. Once you get that, you multiply it by the number of triangles, 5. The work should look something like this:
20/4 = 5
5 x 5 = 25
c) For this one you have to add the total number of students within the ratio. Since there 5 girls and 2 boys, that is 7 people in total. Since you’re trying to reach a total of 28, you divide 28 by 7, which will give you 4. Now, you multiply 4 by the number of just girls, (5), which gives you a total of 20.
