You have the points right? Just chose a graph and plug in the coordinates for one.

the slope of the graph is 3 ( because of the 3x) and the intercept on the y axis = 2

Therefore C

I believe you understood the previous explanation offerred by welshfella. Just apply the slope of 3 and y intercept of 2 to get the answer. Notice that in C, when x=0 y=2, on the other hand when x=-3, y=-1 because 2-3=-1. jLet me know if you understand. I can go further into details if you choose.

I would assign x values for this equation... draw it on paper and compare it to the choices.

let x = -2,-1,0,1,-2

to find the slope of the graph plug in the values of 2 points in the formula y2 - y1 / x2 - x1 where (x,1y1) and (x2,y2) are the 2 points. for graph C (x1,y1) = (-1.-1) and (x2,y2) = (0,2) so for graph C we have (2 - (-1)) /( 0 - (-1)0 = 3/1 = 3
