Question

Which equation is shown on the graph?


A.

y = 2x + 2








B.

y = x + 2








C.



y = x – 2









D.

y = 2x

Answer 1

So where does the the graph intercept the y-axis?

Answer 2

-2

Answer 3

opps y is 2

Answer 4

Yeah so you already know your answer will have +2 in it.

Answer 5

so its a or b?

Answer 6

Do you want me to give you the answer, or help you solve it?

Answer 7

no I want you to help me solve it

Answer 8

You have to find the slope. If you have a hard time doing that use the formula: \[\left( y-y1 \right)\div(x-x1)\]

Answer 9

Actually that's wrong... it should be \[(y2-y1)/(x2-x1)\] Sorry 'bout that.

Answer 10

ok

Answer 11

so it will be a

Answer 12

No.... Another way to figure this out is to plug in the "x" values. if you were to plug in 2(1) +2, you would get four. But on the graph, when "x" is one you would get 3! in this case the answer is y=x+2. To check this: y= (1)+2. You would get 3.

Answer 13

oooh ok I get it now thank you

Answer 14

No problem.
