Answer:
y=(1/5)x
Step-by-step explanation:
First, we must find the slope of the line. 
The slope of a line can be found using the formula: (y2-y1)/(x2-x1)
(3-0)/(15-0)
(3)/(15)
1/5
The slope is 1/5.
Next we find the y-intercept, or where the line crosses the y-axis. In this case, the y-intercept is 0. 
This gives us the equation: y=(1/5)x

Answer:
Option B.  The equation has a maximum value with a y-coordinate of -21.
Step-by-step explanation:
The correct quadratic equation is

This is a vertical parabola open downward (the leading coefficient is negative)
The vertex represent a maximum
Convert to vertex form
Factor -3

Complete the square


Rewrite as perfect squares

The vertex is the point (2,-21)
therefore
The equation has a maximum value with a y-coordinate of -21
