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

The equation y = 2x-2 can be written as y = 2x+(-2)

Adding a negative number is the same as subtraction. Eg: 2+(-3) = 2-3

The equation y = 2x+(-2) is in the form y = mx+b where
m = 2 is the slope
b = -2 is the y intercept

Therefore the final answer is simply -2

The graph crosses the y axis at -2 on the vertical number line. The y intercept as an ordered pair is (0,-2). The x coordinate is always 0 for the y intercept.
