−2x+1/2y=18

x-intercept is when y = 0

so

-2x = 18

x = -9

Answer

x-intercept : (-9, 0)

Answer:

x-intercept is -9

Explanation:

To find the x-intercept, all we have to do is to plug in zero for the y variable in the equation given and then solve for x.

Y=0

−2x+1/2 y =18

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

-2x + 0 = 18

-2x = 18

We will divide both-side of the equation by -2 to get the value of x

-2x/-2 = 18/-2

(On the left-hand side of the equation, -2 at the numerator will cancel-out -2 at the denominator, leaving us with just x, while on the right-hand side of the equation 18 will be divided by -2)

x = 18/ -2

x =-9

Therefore the x-intercept is -9
