Question

What is the x-intercept of the line with the equation 1/3x+y=-15

Answer 1

The x-intercept is for y = 0.

substitute y = 0 to the equation of the function:

$\dfrac{1}{3}x+y=-15\\\\\dfrac{1}{3}x+0=-15\\\\\dfrac{1}{3}x=-15\qquad\text{multiply both sides by 3}\\\\\boxed{x=-45}$

Answer: x-intercept = -45 → (-45, 0).
