What are the x-intercept and the y-intercept of the graph of 9x − 7y = −63?

x-intercept: 7; y-intercept: −9

x-intercept: −9; y-intercept: 7

x-intercept: 9; y-intercept: −7

x-intercept: −7; y-intercept: 9

1 answer

To find the x-intercept, set y = 0 and solve for x:

9x - 7(0) = -63
9x = -63
x = -7

So the x-intercept is -7.

To find the y-intercept, set x = 0 and solve for y:

9(0) - 7y = -63
-7y = -63
y = 9

So the y-intercept is 9.

Therefore, the x-intercept is -7 and the y-intercept is 9.

Therefore, the correct answer is x-intercept: -7; y-intercept: 9.
