Answer 3

you can find the slope based on the two points. Do you know any methods that use points?

Answer 4

no

Answer 5

that's ok! Do you know what the slope represents (i.e. how it relates X to Y)?

Answer 6

not really im not real good at this kinda stuff :[

Answer 7

Answer 8

that's ok!

So the slope of a line gives the main relation between the change in X and Y, and actually represents the change in Y divided by the change in X.

For example, if the equation was y=2x, you could rewrite it as y=2/1x. That means that every time x changes by a value of 1, y changes by 2.

Can you see how this could be done with two points?

Answer 9

yea

Answer 10

walk me through what you do. I'll confirm your answer, or help you if you get stuck/make a mistake.

Answer 11

would the answer be d

Answer 12

since it changes by 2

Answer 13

the change in Y is equal to (6-0) = 6
the change in X is equal to (0--3) = 3

slope is equal to Y/X = 6/3 = 2, which is D.

Answer 14

oohhh.. ok thank you for you help :)

Answer 15

always make sure you keep the same point as point 1 and point 2 - you get different answers (in this case, it would have been negative) if you can't keep them straight.

You're welcome!
