The line touching the point (0,3) goes to the equation y= 2x + 3 because + 3 represents the y-intercept. The line touching (0,-2) goes to the equation y = 2x - 2 because - 2 represents the y-intercept as well.
The upper line has the y-intercept +3; the lower line has the y-intercept -2. This should make it simple for you to identify which graph matches which equation.
