Question:

Find the equation whose graph is shown below. Write your answer in standard form.

(Standard form is A (x) + B (y) =C, where A is positive, and A, B, and C are integers with the greatest common divisor 1.)

Points (3,0) and ( -1,-1) are on the graph

Slope = [ 0 - -1 ] / [ 3 - -1] = 1/4

Using (3,0)

y =(1/4) ( x -3)

y =(1/4)x - 3/4 multiply through by 4

4y = 1x -3

1x - 4y = 3
