# Find the Slope and Y-Intercept (-8,1) , (-5,1) (-8,1) , (-5,1)
Find the value of the slope.
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=1-(1)-5-(-8)
Simplify.
Simplify the numerator.
Multiply -1 by 1.
m=1-1-5-(-8)
Subtract 1 from 1.
m=0-5-(-8)
m=0-5-(-8)
Simplify the denominator.
Multiply -1 by -8.
m=0-5+8
Add -5 and 8.
m=03
m=03
Divide 0 by 3.
m=0
m=0
m=0
Find the value of the y-intercept.
Substitute the value of m into the slope-intercept form of the equation, y=mx+b.
y=(0)⋅x+b
Substitute the value of x into the slope-intercept form of the equation, y=mx+b.
y=(0)⋅(-8)+b
Substitute the value of y into the slope-intercept form of the equation, y=mx+b.
1=(0)⋅(-8)+b
Rewrite the equation as (0)⋅(-8)+b=1.
(0)⋅(-8)+b=1
Simplify (0)⋅(-8)+b.
Multiply 0 by -8.
0+b=1
Add 0 and b.
b=1
b=1
b=1
The values of the slope and y-intercept are m=0 and b=1.
m=0
b=1
