y-intercept = -2
x-intercept =?
Step 1 ; Use the given information to derive the equation of the line.
Substitute values into ; y=mx+b
Where m = slope
b = y-intercept
Equation = 
Step 2 ; Calculate the x-intercept
Arrange the equation in standard form ; Ax +By = C

Let y = 0

Cross Multiply

So ; (4,-2)
