Answer:

$y=3x+6$

Step-by-step explanation:

<u>Equation of the line</u>

The equation of the line in slope-intercept form is:

$y=mx+b$

Being m the slope and b the y-intercept.

We are given two points for the required line: The x-intercept is -2, thus the point is (-2,0), and the y-intercept b=6 represents the point (0,6).

Since the value of b is 6, we use the first point to find the slope:

$0=m(-2)+6$

Solving:

m=3

The correct equation of the line is:

$\boxed{y=3x+6}$

The path of a ball kicked from the ground can be modeled by the equation y=−1/5(x−5)(x−20), where x and y are measured in feet.

Answer:

Step-by-step explanation:

This is already factored for the zeros of the quadratic. If x - 5 = 0 and x - 20 = 0 then x = 5 and 20. The ball was kicked 5 feet out and landed at 20 feet down the field. The difference is 15 feet. That's how far the ball traveled from its initial position on the ground to its landing place.

So 15 feet from where it was kicked.
