The slope of the equation would be 7/3 since the original slope was -3/7. We already know y int (b) so the eqn is
y = 7/3x + 2
Answer:
Since time can't be negative, the only possible solution is 0.72 s.
Step-by-step explanation:
When the ball hits the ground its height is equal to 0, so we must find a value for "t" that results in h = 0. We have:

Since time can't be negative, the only possible solution is 0.72 s.
