Question

Identify the correct x intercept and y intercept of the equation 2x - 3y = -18.

x intercept = (9, 0); y intercept = (0, -6)

x intercept = (6, 0); y intercept = (0, -9)

x intercept = (-9, 0); y intercept = (0, 6)

x intercept = (-6, 0); y intercept = (0, 9)

Answer 1

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

Answer 3

Alright, that's fine. So if you let y=0, you are left with:
$$2x - 3(0) = -18 \ \ \ \ \ \ \text{we know 3(0)=0, so} \\
\Rightarrow 2x = -18 \ \ \ \ \ \ \ \text{divide by 2,} \\
\Rightarrow x = -9$$
Thus your x-intercept is the point (-9,0). Try the same thing with the y-intercept and you'll find that to be (0,6). Good luck!
