the answer is b, y=3x-1. so the equation you’re looking at is y=mx+b, with m being slope and b being the y intercept. it says the slope is equal to 3. to find the y intercept, use the slope to find the other points. using the slope, you can find that the point of the y intercept is (0, -1), so your equation would be 3x-1. i hope this helps!!
