Question

What is the x-intercept of the line with the equation -2x + 1/2y = 18?

Answer 1

-2x + (1/2)y = 18

(1/2)y = 2x + 18

y/2 = 2x + 18

y = 2*(2x + 18)

y = 2*2x + 2*18

y = 4x + 36

The x intercept is the value of x, when the y value is 0.

0 = 4x + 36

0 - 4x = 36

-4x = 36

x = 36/-4

x = -9

The x intercept is  -9

I hope this helps.  

Answer 2

Answer:

The x-intercept of the line with the equation is -9.              

Step-by-step explanation:

Given : Equation $-2x+\frac{1}{2}y=18$

To find : What is the x-intercept of the line with the equation ?

Solution :

To find x-intercept we put y=0.

Equation $-2x+\frac{1}{2}y=18$ substitute y=0,

$-2x+\frac{1}{2}(0)=18$

$-2x=18$

$x=\frac{18}{-2}$

$x=-9$

Therefore, The x-intercept of the line with the equation is -9.
