PLS HELP ASAP!!!

What is the x-intercept of the line with this equation 1/3x +y=-15?
Enter your answer in the box.


(_,0)

Answer 1

x- intercept = -45

Explanation:

equation: 1/3x + y = -15

=> to find intercept, y=0

=> 1/3x + 0 = -15

=> 1/3x = -15

=> 1x = -15 × 3

=> x = -45 / 1

=> x = -45

Answer 2

(-45,0)

Explanation:

We know that the x intercept is the point where y equals '0' in an equation. Which means in a function including the y value as a variable, we can substitute 0 for y to get the x intercept!

Here's how you do it:

`1/3x + y = -15\\y=0\\1/3x + (0) = -15\\1/3x = -15\\x = -45`

That makes the x intercept -45!
