Write the equation represented by the graph below.
alexira [117]

Answer:

y=3/10x

Step-by-step explanation:

First, use the formula y2-y1/x2-x1. Pick any two points from the line to put into this formula. In this case, I would pick (0,0) and (20,6) cause I'm lazy lol. Plot these points into the formula. It would look like this 6-0/20-0. Simplify this to get 6/20. The GCM of 6 and 20 is 2 so divide 2 in each side to get 3/10. Because the y-intercept is on 0, there is no y-intercept. Therefore, the equation is y=3/10x
