To find the x-intercept of a line, we set y to zero in the equation and solve for x.
So, let's substitute y = 0 into the equation −2x + (1/2)y = 18:
−2x + (1/2)(0) = 18
−2x = 18
To isolate x, we divide each side of the equation by -2:
x = 18/(-2)
x = -9
Therefore, the x-intercept of the line with the given equation is -9.
