Given the equation y=3x - 7, state the y- intercept and slope of the line. Describe how you would graph this line.

Y= mx + b, so the 3 represents the slope and the -7 represents the y intercept. This line can be graphed by placing a point at (0 , -7) then I would count up 3 spaces and to the right 1 space, placing another point at (1, -4). I would connect those dots and extend my line through them.
