Point F = (-2,-3); Apply the midpoint formula, (x1+x2/2),(y1+y2/2) = (x,y).
-6+2/2
-4/2
x=-2
-2+(-4)/2
-6/2
y=-3
(x,y)=(-2,-3)
The equation would be y = 60x + 20
The average cost represents the slope of the line of the graph.
Increasing the slope of the graph increases the steepness of the line.
Therefore,
increasing the average cost of gas from $1.50 to $2.20 will increases
the steepness of the line. (i.e. the line becomes closer to the vertical
line).
We know area of triangle = 
In triangle ABC , AB is the base and BC is the height
Now we find the distance between A and B
Distance formula is 
A(0,3), B(7,3)
Distance AB = 
=
= 7
B(7,3), C(7,7)
Distance BC = 
=
= 4
area of triangle = 
area of triangle = 
=
= 14
