Answer:

x = - 9 (negative 9)

Step-by-step explanation:

The x intercept is where y = 0. When y = 0, the point is on the x axis.

So use the equation and replace y with 0.

-2x + 1/2y = 18

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

-2x + 0 = 18

-2x = 18

x = - 9

Check you answer by putting your answer for x into the equation. See if it does make y = 0

-2x + 1/2y = 18

-2(- 9) + 1/2y = 18

18 + 1/2y = 18

1/2y = 0 so y must also equal 0

Complete question :

Tom will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $57.98 and costs an additional $0.14 per mile driven. The second plan has an initial fee of $53.98 and costs an additional $0.16 per mile driven. How many miles would Tom need to drive for the two plans to cost the same?

Answer:

200 miles

Step-by-step explanation:

Let miles driven = x

First option :

57.98 + 0.14x

Second option :

53.98 + 0.16x

First option = second option

57.98 + 0.14 = 53.98 + 0.16x

57.98 - 53.98 = 0.16x - 0.14x

4 = 0.02x

x = 200

200 miles
