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

Step-by-step explanation:
The answer is -2.5. this is how you work it out.
21.4 + (-23.9) = -5/2 = -2.5
