Answer:
The equation of the line is
, that passes through points 
Step-by-step explanation:
Given points are 
We need to write the equation of the line that passes through these points
First, we will find slope of this line

So, our slope is
. Now, we will plug the point
in the equation below.

So, the equation of the line is
.
The parabola opens down, since the 'a' value of the equation is a negative value.
