Y - y1 = m(x - x1) slope(m) = -6 (-2,-3)...x1 = -2 and y1 = -3 now sub and pay close attention to ur signs y - (-3) = -6(x - (-2)....we're not done yet... y + 3 = -6(x + 2) <===
I don’t know if you meant 7 hours or 7 1/2 hours, but if it was in 7 hours, the answer would be around 15 square feet. If it was 7 1/2 hours, it would be 14 square feet.
