Question

A piecewise-linear function is shown below. The horizontal range is from 0 to 30 and the Xscl is 5. The graph of the function passes through (0, 0) and (30, 0).

Answer 1

For the first one I would say that the rise over run is 10/2 or 5 but I do not see a y intercept so I think the answer would be y=5x but that does not look right?

Answer 2

I am confused because I am not sure how to write a formula when I am only given a point (10, 2)

Answer 3

look again and you will see 2 lines
line 1 points (0, 0) and (10, 2)
line 2 points (10,2) and (30, 0)

Answer 4

hint for line 1 the slope is positive for line 2 the slope is negative

Answer 5

oh because for line one it is going up and line to is going downward
