Answer 1

Can someone walk me through how to do this? http://prntscr.com/5j6f8i

Answer 2

do you see the \(y\) intercept?

Answer 3

yeah, -80

Answer 4

ok so you know it will be \[y=mx-80\] you need \(m\)

Answer 5

Now what?

Answer 6

find the slope.

Answer 7

your y-intercept is:
(0,-80)

and choose any other point on the graph, and then use a slope formula.

Answer 8

Could I choose any 2 points?

Answer 9

use your eyes to find the slope

Answer 10

i can't get the draw tool to work
count how many spaces you go to the right, then how many you go down

Answer 11

Okay, I know what you mean though, thanks

Answer 12

or pick two points, say \((0,-80),(80,-90))\ to compute the slope

Answer 13

\[(0,-80),(80,-90)\]
