Question

Use the slope formula to determine the slope of the line that passes through the points A(-5, 9) and B(-5, 6).

Answer 1

Answer:

  undefined

Step-by-step explanation:

The slope formula tells you the slope is ...

  m = (y2 -y1)/(x2 -x1)

Fill in the point coordinates, we find the slope to be ...

  m = (6 -9)/(-5 -(-5)) = -3/0

This slope is undefined.

___

It means the line is a vertical line. The constant must match the x-coordinates of the points:

  x = -5 . . . . the line through the given points
