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).
Substitute in the values of x and y into the equation to find the slope.
Simplify the numerator.
Multiply -1 by 10.
Subtract 10 from 10.
Simplify the denominator.
Multiply -1 by 8.
Subtract 8 from -4.
Divide 0 by -12.
Find the value of the y-intercept.
Substitute the value of m into the slope-intercept form of the equation, y=mx+b.
Substitute the value of x into the slope-intercept form of the equation, y=mx+b.
Substitute the value of y into the slope-intercept form of the equation, y=mx+b.
Rewrite the equation as (0)⋅(8)+b=10.
Multiply 0 by 8.
Add 0 and b.
The values of the slope and y-intercept are m=0 and b=10.
