you can check if its right youreslf

OpenStudy (dan815):

plug in the points and see if it works

how

OpenStudy (dan815):

it says (0,-3) is a point on this line since its the y intercept

OpenStudy (dan815):

and slope = -4 so that means -4/1 or 4 down in y axis for ever 1 in x

OpenStudy (dan815):

you can plot points and see if the equation satifies
