Question

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

Answer 1

The y-intercept is located at -2. In the formula y=mx+b, b is the y intercept.

Answer 2

The equation is here: y = mx + b
m = slope
b = y intercept

The 'm' in y = 2x - 2 is 2, therefore, making the slope equal to 2. 

The 'b' in y = 2x - 2 is 2, therefore, making the y intercept equal to -2. 

Answer should be that the y intercept is -2.
