What is the x-intercept of the line with the equation -2x + 1/2y = 18 ?
( 0 )

-2x+1/2y=18

[When finding the x-intercept, we need to make y as 0]

-2x+1/2(0)=18

-2x=18

2x/2=18/2

x=9

Therefore, the x-intercept is (9,0)

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

or
