# Find the Slope and Y-Intercept (-1,0) , (-2,-5) (-1,0) , (-2,-5)
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=-5-(0)-2-(-1)
Simplify.
Simplify the numerator.
Multiply -1 by 0.
m=-5+0-2-(-1)
Add -5 and 0.
m=-5-2-(-1)
m=-5-2-(-1)
Simplify the denominator.
Multiply -1 by -1.
m=-5-2+1
Add -2 and 1.
m=-5-1
m=-5-1
Divide -5 by -1.
m=5
m=5
m=5
Find the value of the y-intercept.
Substitute the value of m into the slope-intercept form of the equation, y=mx+b.
y=(5)⋅x+b
Substitute the value of x into the slope-intercept form of the equation, y=mx+b.
y=(5)⋅(-1)+b
Substitute the value of y into the slope-intercept form of the equation, y=mx+b.
0=(5)⋅(-1)+b
Rewrite the equation as (5)⋅(-1)+b=0.
(5)⋅(-1)+b=0
Multiply 5 by -1.
-5+b=0
Add 5 to both sides of the equation.
b=5
b=5
The values of the slope and y-intercept are m=5 and b=5.
m=5
b=5
