Step-by-step explanation:
<h2>
Answer:</h2>
If the line is parallel to the one given, their slopes are the same, so we need to find the y-intercept, then we can determine the slope-intercept form parallel to the given line.

Now that we have the y-intercept, we can create the equation.

We can prove this by graphing both lines, like so.
-1.9 = x/.5 given equation
multiply both sides by .5
.5(-1.9) = x/(.5) *(.5)
-.95 = x
check: -1.9 = -.95/ .5

is a right triangle with base length 1 and height 8, so the area of

is

.
The average value of

over

is given by the ratio

The denominator is just the area of

, which we already know. The average value is then simplified to

In the

-plane, we can describe the region

as all points

that lie between the lines

and

(the lines which coincide with the triangle's base and hypotenuse, respectively), taking

. So, the integral is given by, and evaluates to,



3-4 = -1
