Slope=-1.8, X=-0.5, y=1.9
Equation is y^2-y^1=m(x^2-x^1).
Y-1.9=-1.8(X-(-0.5))
Y-1.9=-1.8x+0.90
Add 1.9 on both sides.
Y= -1.8x+1.
I hope this helps you.
Answer:
<em>t = 5 seconds</em>
Step-by-step explanation:
We must solve the equation of movement of the ball as a function of time in seconds.
We must find how many seconds it takes until the ball touches the ground. When the ball touches the ground, the height b (t) = 0
Then we equate the equation to zero and solve for t.

Use the quadratic formula.
Where


We take the positive solution
