The relationship between the time since the ball was thrown and height of the ball can be modeled by the equation h 32t-16t2+ 4, where h is the height of the ball after t seconds. complete the square to find how long it will take the ball to reach a height of 20 ft

-2/3

Step-by-step explanation:

The formula for slope is

You have two coordinate points (-6,7) and (0,3)

Pick either point to be (x1, y1) and then the other is (x2, y2)

plugging these values into the slope formula you will get the answer

I decided to pick (-6,7) as (x1, y1) and (0,3) as (x2, y2) so it looks like this when I plug it in:

simplifying you get the

So the final answer simplifies to -2/3 and that is the slope of the line
