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
