Answer 1

The x-intercept is (-7/5, 0), and the y-intercept is (0, 7/3).

Step-by-step explanation:

To find the x-intercept, set y = 0 in the equation and solve for x. Substitute y = 0 into the equation:

15x - 9(0) = -21 → 15x = -21 → x = -21/15 = -7/5

So the x-intercept is (-7/5, 0).

To find the y-intercept, set x = 0 in the equation and solve for y. Substitute x = 0 into the equation:

15(0) - 9y = -21 → -9y = -21 → y = -21/-9 = 7/3

So the y-intercept is (0, 7/3).
