The slope of the graph of the equation y=2x-2 is 2. what is the y intercept?

The equation y= 2x-2 follows the same form as y=mx+b. In y=mx+b, the letter "b" represents the y-intercept. The letter "m" represents the slope.

To solve this try writing the equation underneath y=mx+b:
y=mx+b
y=2x-2 

From this we can see, m=2 and b=(-2) (it is negative because 2 is being subtracted rather than added).

Another way to find the y-intercept is pluging in 0 for x into the equation.This is because the y intercept is the y vale on a point where x=0.

y=2x-2
y=2(0)-2
y=0-2
y=-2
