Write an equation with the two points: (5,-2) and (3,4)
eimsori [14]

Answer:

y=-3x-17

Step-by-step explanation:

To find out the m(slope) of the equation use the formula:

\frac{y_2-y_1}{x_2-x_1}.

Substitute the values:

\frac{4--2}{3-5}

Combine the values:

\frac{6}{-2}

Find the value of the fraction:

-3

M is -3.

The equation so far is y=-3x+b

To find the y intercept, substitute one pair of coordinates into the equation and solve for b:

y=-3x+b\\-2=3*5+b\\-2=15+b\\-17=b.

We see that b =-17 so the full equation would be:

y=-3x-17.

the maximum height the ball will reach is equal to the y-coordinate of the vertex of the equation

So we need firstly, the vertex of the given quadratic equation

The vertex can be obtained by the use of plot of the graph

By doing this, we have it that the vertex is at the point (3,72)

Thus, we can conclude that the maximum height the ball can reach is 72 ft
