Slope is 3 and y-intercept is -4


Your line equation is in the form #y=mx+b#. The "m" is the symbol for slope and the "b" is the symbol for the y-intercept. Therefore, the 3 is the m value (for your slope) and the -4 is the b value (for your y-intercept).

Another way to help you remember is that the slope is always the number next to the "x", and the y-intercept is always the number on it's own. But this only applies when your line is written in the form of #y=mx+b#.
