Math
(6,12) , (-6,-2)
Find the value of the slope.
Tap for more steps…
Slope is equal to the change in y over the change in x, or rise over run.
m=change in ychange in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m=y2-y1x2-x1
Substitute in the values of x and y into the equation to find the slope.
m=-2-(12)-6-(6)

Find the value of the y-intercept.
Tap for more steps…
Substitute the value of m into the slope-intercept form of the equation, y=mx+b.
y=(76)x+b
Substitute the value of x into the slope-intercept form of the equation, y=mx+b.
y=(76)⋅(6)+b
Substitute the value of y into the slope-intercept form of the equation, y=mx+b.
12=(76)⋅(6)+b
Rewrite the equation as (76)⋅(6)+b=12.
(76)⋅(6)+b=12
Cancel the common factor of 6.

Cancel the common factor.
76⋅6+b=12
Rewrite the expression.
7+b=12
7+b=12
Move all terms not containing b to the right side of the equation.

Subtract 7 from both sides of the equation.
b=12-7
Subtract 7 from 12.
b=5
b=5
b=5
The values of the slope and y-intercept are m=76 and b=5.
m=76
b=5
