So the solution to this problem was supposed to be -3:
"Since the slope of the line is 4, we know that the rise over run is 4/1. Therefore, for every increase of 1 in x, there is an increase of 4 in y. Starting from (-3, 5), we can move 2 units to the left and 8 units down to get to the x-axis. Therefore, the y-coordinate of the point where the line intersects the x-axis is 5 – 8 = -3."
I don't see how they got -3 and not 0...what am I not understanding?
p.s. this is a "hard" GRE quantitative reasoning ques

Okay that's a much better explanation, however I'm still lost. Why do we need to move "two units to the right along the x-axis" to reach the x-axis?? How did you determine this? I'm having trouble visualizing what you are talking about...

- Find the intersection of the lines L1 and L2, where L1 is the line through the points (0, -13) and (5, -3) and L2 is the line with the slope -3/4 and the y-intercept equal to 3/4. Thank youarrow_forwardThis was supposed to be proven by not using the slope formuarrow_forwardFind the slope between the points (4/3,4/13) and (19/3,18/13)arrow_forward
