Answer:
Missing co-ordinate for the ordered pair is 
Y-intercept is 
X-intercept is 
Step-by-step explanation:
The number of a certain company's video stores can be approximated by the linear equation

where
is the number of stores and
represents the number of years after 1990.
To find the missing co-ordinate for the ordered pair solution 
For the ordered pair, we are given the
value which is =7 i.e 7 years after 1990. Thus we will plugin
in the linear equation to get the
value which is number of stores after 7 years from 1990.



Thus the ordered pair is 
To find y-intercept which is the point where the line touches the y-axis, we would plugin
in the equation as the x-coordinate is 0 at y-axis.



Thus y-intercept is at point 
To find x-intercept which is the point where the line touches the x-axis, we would plugin
in the equation as the y-coordinate is 0 at x-axis and thus for 

Subtracting both sides by 4682.


Dividing both sides by -264


∴ 
Thus x-intercept is at point 
You have to find the area of each face and add them all together. You also need to find the unknown side which is indicated in the picture i attached.
