I've been given a problem on finding the y-intercept, and i've been given one set of points (along with the slope) to find out the y-intercept. Now, I'm not allowed to graph, and I dont know any equation on finding the y-intercept, so can anyone help out?

Use the point (x,y) and the slope (m) and plug it into the equation above. Plugging in y, x, and m will only leave you with b and you can solve for the y-intercept.
It's good to know that is called the "point-slope" form of a line..if my memory serves me correctly.
AHH!! I knew it didn't sound right..hence the disclaimer at the end. I had the epiphany as I was eating my dinner and was going to come back and edit my comment..but you caught me!! :)
