Each pair of points lies on a line with the given slope. Find x.

Points: (2, 4), (x, 8); Slope = -2

Asked by charliez

Answer (2)

I am slightly confused with your question. Are you looking for the equation or for x?
Anyway, here is both:
If you are finding the equation of the line, plug in your numbers in the equation y=mx+b. Use the point (2,4). 4=-2(2)+b Solve for b. 4=-4+b 8=b Then, put the slope and y-intercept in slope-intercept form. y=mx+b. y=-2x+8 Now you have the equation.
If you are solving for x, plug the point (x,8) in your equation. y=-2x+8 8=-2x+8 Solve for x. -2x=0 x=0

The value of x is 0 based on the given points and slope. This was found using the formula for slope between two points. By solving the resulting equation, we determined the value of x accurately.
