Answer: \boxed {(-6,0)}

Explanation:

The x-intersection coordinate of the equation 3x+2y=-18 is (x,0)

Hence, y=0

3x+2(0)=-18

3x+0=-18

3x=-18

Divide both parts of the equation by 3:

x=-6

Thus, (-6,0)

Explanation:

3x + 2y = -18

Set y = 0

3x + 2 × 0 = -18

3x + 0 = -18

3x = -18

x = -6

.: the x-intercept = -6

You can choose to put it in coordinate form (-6, 0).
