Find the Slope and Y-Intercept (2,2) , (-6,-2)

Math
(2,2) , (-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-(2)-6-(2)

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=(12)x+b
Substitute the value of x into the slope-intercept form of the equation, y=mx+b.
y=(12)⋅(2)+b
Substitute the value of y into the slope-intercept form of the equation, y=mx+b.
2=(12)⋅(2)+b
Rewrite the equation as (12)⋅(2)+b=2.
(12)⋅(2)+b=2
Cancel the common factor of 2.

Subtract 1 from both sides of the equation.
b=2-1
Subtract 1 from 2.
b=1
b=1
b=1
The values of the slope and y-intercept are m=12 and b=1.
m=12
b=1
