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 8.
Subtract 8 from 4.
Simplify the denominator.
Multiply -1 by 0.
Add 3 and 0.
Move the negative in front of the fraction.
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 (-43)⋅(0)+b=8.
Multiply 0 by -1.
Multiply 0 by 43.
Add 0 and b.
The values of the slope and y-intercept are m=-43 and b=8.
