Question

Find the slope of line passing through the points (5, 9) and (5, -2)
A. -11
B. 0
C. 11
D. undefined

Answer 1

The slope formula is "rise over run", or
(y2-y1) / (x2-x1).

Can you compute that?

Answer 2

Do you want the answer or learn how to do it?

Answer 3

both

Answer 4

Try using the slope formula and see what happens.

Answer 5

im working on it

Answer 6

cool :)

Answer 7

its -11

Answer 8

well the numerator is 11 but the bottom (denominator) you probably got 0 right?

Answer 9

so its not a negative its possitive 11

Answer 10

Yeah it's -11, that part you got right, but the bottom of the fraction is 0 - that's the part I was trying to draw your attention to. What happens when you divide by 0?

Answer 11

You can't divide by 0, it's undefined. The answer is D.

Answer 12

gradient is undefined
