How do you find the slope & y-intercept of the equation y= 3x-4?

Slope is 3 and y-intercept is -4

Explanation:

Your line equation is in the form $y = m x + b$. 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 $y = m x + b$.
