do u know what the y intercept is?

OpenStudy (anonymous):

no "/ i dont understand it at all its my last question on my homework

OpenStudy (anonymous):

it's when x is 0. and there's only one point on the graph where that is

OpenStudy (anonymous):

when y=-1 x=0, and that's the first part

OpenStudy (anonymous):

remember on the lat question that y=mx+b where b is the y-intercept

OpenStudy (anonymous):

so is the answer y=-1(x+b)

OpenStudy (anonymous):

not yet to find slope you need the change in y over x, and by counting it looks like it would be 2/3

OpenStudy (anonymous):

plugging in the numbers would be \[y=\frac{ 2}{ 3 }x-1\]

OpenStudy (anonymous):

ohhhh...but how

OpenStudy (anonymous):

look at the graph again. count from (0,-1) to (3,1).
