Answer 1

okay so first lets pick to points

Answer 2

we will do (15,5) and (30,10) do you agree?

Answer 3

sure

Answer 4

*wondering where 30,10 is at *

Answer 5

how did you get 30,10

Answer 6

its not on the graph

Answer 7

if the graph were to keep going that would be the next point

Answer 8

by scrolling off the screen methinks =)

Answer 9

but why not pick something thats on the graph that we can see

Answer 10

there is only one point visible

Answer 11

if you were to extend the line it would make a point at (30,10)

Answer 12

so the slope intercept form is y2-y1/x1-x2

Answer 13

that means subtract both y intercepts and then both x intercepts

Answer 14

mmm so we plug them in

Answer 15

\[\frac{ 10-5 }{ 30-15 }\]

Answer 16

what does that give you?

Answer 17

5/15
