Question

What is the slope of the line passing through (0,3) and (4,5)?

a)0.5
b)2
c)-2
d)-0.5

Answer 1

right away you need to use the slope formula: (y2-y1)/(x2-x1)

Answer 2

okay

Answer 3

pick either of your coordinates to be your sub 2 and the other as your sub 1 and just fill them in!

Answer 4

wait....

Answer 5

what?

Answer 6

Ok you have (0,3) and (4,5), right? Either of these group of coordinates can be treated as the little 2. So, for instance, maybe we'll use 0,3 to be our x2 and our y2. And for the (4,5) we'll let 4 be x1 and 5 be y1.

Answer 7

I'll draw it, too.

Answer 8

oh okay thx!
