-2,000
2,000
3,000

Answer 2

the answer would be the slope.

Answer 3

Do you know the slope formula?

Answer 4

y-y1=m(x-x1)

Answer 5

\[\frac{ y _{1}^2 - y_{2}^2 }{ x_{1}^2 - x_{2}^2 }\]

Answer 6

ohh that one

Answer 7

What you put was the point slope formula

Answer 8

not formula, but more of a form. Anyway, you would pick 2 points on the graph.

Answer 9

So now this is where I dont know how which is y and x

Answer 10

Okay ill walk you through. Pick two points.

Answer 11

oh okay so (0,80,000) and (10,50,000)

Answer 12

Okay. So our Y's are 80,000 and 50,000. Notice that there is a y1 and x1 and y2 and x2. These correspond, so you cannot randomly put them in whatever order you want.

So we will do this

80,000-50,000.

Our corresponding x's are 0 and 10, so they go under, as so.

\[\frac{ 80,000 - 50,000 }{ 0- 10}\]

Answer 13

I just did it and I got 3.. for 3,000

Answer 14

-3,000 actually because its goin down

Answer 15

Correct?

Answer 16

well, you have forgotten one thing. when you subtract 0-10, equals NEGATIVE 10. so it is -3000 like you stated.

Answer 17

Thank you!

Answer 18

Np

Answer 19

You know thats all I have trouble with, finding what formula to use

Answer 20

do more practice problems, it will help a lot. the more often you start using the right ones in the right situations, you will get better at it.

Answer 21

okay
