Question

HELP HELP HELP What is the x-intercept of the line with this equation −5x+15y=15 ?
<3

Answer 1

x = - 3

Explanation:

To get the x intercept, y has to be equal to 0.

- 5·x + 15·y = 15

- 5·x + 15·0 = 15

- 5·x = 15

x = 15/(- 5)

x = - 3

Answer 2

Answer: (-3, 0)

Step-by-step explanation: Isolate the y variable, so you get 15y = 15 + 5x, then divide by 15, y = 1 + 1/3x. To get the x intercept, the y has to be equal to 0, so we get 0 = 1 + 1/3x.

0 = 1+1/3x

-1 = 1/3x

-3 = x
