Answer:
0
Step-by-step explanation:
the y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0 (Wikipedia).
If you put this into a graphing calculator, and look at the y-axis which the vertical line down the centre of the screen, you will see that the function goes through the origin which is (0,0), so your y-int of 0.5 is 0.
