Answer 2

The slope (m) is the change in "y" over the change in "x":\[m = \frac{ y _{2} - y _{1} }{ x _{2} - x _{1} }\]I suggest taking as your 2 points:

(0, -1) and (5, 3) for your\[(x _{1}, y _{1})\]and\[(x _{2}, y _{2})\]

Answer 3

All good now, @faded911 ?

Answer 4

So it comes out a 1/2?

Answer 5

How did you get that?

Answer 6

You will benefit by identifying\[x _{1}, x _{2}, y _{1}, y _{2} \]Hint: take them from the points I identified in my first post and then substitute them into the formula I wrote out for you. Do show your work.

Answer 7

How's this going for you, @faded911 ?

Answer 8

So as a fraction are the x's or y's on top?

Answer 9
