Find the slope of the line passing through the points (-7, 4) & (-7, -8)

Undefined

Step-by-step explanation:

The equation for finding the slope is:

y2 - y1

x2 - x1

4 - (-8)

-7 - (-7)

4 + 8

-7 +7

12

0

The slope is Undefined, so there is no answer

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
