The function y = 4x - 9 includes the ordered pair 6 and what?

By looking at the function, we can tell the slope is 4/1, and the y-intercept is - 9.

By this, we can find the y value for the ordered pair beginning with x-6

0, - 9

1, - 5

2, - 1

3, 3

4, 7

5, 11

6, 15

The y value for the ordered pair beginning with x-6 should be 15.
