Find the slope of the line passing through the points (-7,8) and (-7,-6) Find the slope of the line passing through the points (-9,-8) and (3,-8)

1) undefined

2) 0

Step-by-step explanation:

Slope formula:

Problem 1:

(x1, y1) = (-7, 8)

(x2, y2) = (-7, -6)

Plug those 2 points into the slope formula and solve:

Here, you can't divide by 0, so this slope is undefined. An undefined slope would make a completely vertical line on a graph. In this case, the equation of the line would be just:

Problem 2:

(x1, y1) = (-9, -8)

(x2, y2) = (3, -8)

The slope is 0, and that would make a horizontal line on a graph. The equation would be:

You don't actually need to fully work out the slope that way. If you ever have 2 points with the same x-coordinate, the slope has to be undefined. If you ever have 2 points with the same y-coordinate, then the slope has to be 0, assuming it's linear of course. You can see that in the points given, the first 2 have the same x and the second 2 have the same y.

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
