You can put this solution on YOUR website! The slope (m) is 3 and the y-intercept (b) is -4.
An easy way to graph this (since it is a linear equation) is to plot at least two points.
For instance, when x=0, y=-4. And when x=1, y=-1.
Plot these two points and make a straight line through them - that is your graph. It looks like this:
