Question 315644
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: 

{{{ graph( 500, 500, -10, 10, -10, 10, 3x-4) }}}
