Question

A line has a slope of 4 and contains the point (x/2,7) and (-10,15.) what is the missing x-value for the coordinate point?

Answer 1

We can start by using the slope formula to find the equation of the line:

slope = (change in y) / (change in x)

We know the slope is 4, so we can plug in the coordinates (-10, 15) and (x/2, 7) to solve for x:

4 = (15 - 7) / (-10 - x/2)

Multiplying both sides by (-10 - x/2) gives:

-40 - 2x = 8

Solving for x, we get:

x = -24

Therefore, the missing x-value for the coordinate point is -24.
