Question

Fill in the blanks below.

Answer 1

The first one has no slope because it will be a straight vertical line going through the x-axis. The second one will also be a straight line, except it will be a horizontal line through the y-axis.

Answer 2

The slope for the first one would be:
y2-y1/x2-x1, so replace those with the coordinates and you'll get:
-3-1/-7-(-7) => -4/0 so I guess the slope is zero

the slope for the second one would be:
-3-(-3)/5-(-4)=> 0/9 I think this one would be undefined.
Check to make sure, though!
