Jaime graphed linear data in the form (cost, number). The y-intercept was 0. Jayla graphed the same data in the form (number, cost). What was the y-intercept of her graph? Complete the explanation.

Jaime's graph contained (0,1) (0,0) or (1,0). Since Jayla's data were the same but with the x and y switched her graph also contained (1,0) (0,1) or
(0,0).

I am confused on this and don't know what the proper answer should be. Please help.

  1. if the y-intercept is 0, then y=kx
    That means its inverse is also of the form y=mx, where m = 1/k

    Now the rest should come easy.
