Question

I really need help with this one

Find the slope of the line containing the given points

(-8/7, -9/10) and (7/5, -9/10)

Answer 1

slope = (y2-y1)/(x2-x1)


(x1, y1)= (-8/7, -9/10)
(x2,y2)=(7/5, -9/10)

Answer 2

i know the formula i have just never done it with fractions before, thats the part i need help with

Answer 3

Wait, the y values in both points are the same. That means the line is horizontal.

Answer 4

That means the slope is 0

Answer 5

oh i was think it was undefined but i remember now that's only when it vertical thanks

Answer 6

Yep!
