Question

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

Answer 1

(-45,0)

Explanation:

I took the test

Answer 2

(- 45, 0 )

Explanation:

To find the x- intercept let y = 0 in the equation and solve for x

`(1)/(3)` x + 0 = - 15, that is

`(1)/(3)` x = - 15

Multiply both sides by 3 to clear the fraction

x = 3 × - 15 = - 45 ← x- intercept ⇒ (- 45, 0 )
