Find the slope of the line passing through the points (-6-9) and (9,-9) Find the slope of the line passing through the points (4,1) and (4,-5).

9514 1404 393

Step-by-step explanation:

The slope formula is useful for this.

  m = (y2 -y1)/(x2 -x1)

__

First line:

  m = (-9 -(-9))/(9 -(-6)) = 0/15 = 0

The slope of the first line is zero.

__

Second line:

  m = (-5-1)/(4 -4) = -6/0 = undefined

The slope of the second line is undefined.

It is always a good idea to apply a little critical thinking to the given information. Here, you observe that the y-coordinates of the first pair of points are the same. That means this is a horizontal line, with a slope of 0.

Similarly, you observe that the x-coordinates of the second pair of points are the same. That means this is a vertical line, with undefined slope.

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
