Brent Pace · Answer 1

The x-intercept is found when y=0, and the y-intercept is found when x=0. If y=0, then we have:

2x=24

x=12

Therefore, the x-intercept is 12, so the full coordinates are (12, 0). Note that the only option with this x-intercept is C, so C is the correct answer.

You can find the y-intercept similarly. If x is zero, then:

-6y=24

y=-4

Therefore, (0, - 4) is the y-intercept. This is also part of option C.
