FILL IN THE BLANKS:
when graphing equations in y=mx+b form, the first thing you do is ______ the next thing you do is____
when graphing equations in y=mx+b form, the first thing you do is plot the y-intercept (begin) the next thing you do is use the slope (move) to get a second point and connect the points.
