Ineed with 9-81 asap pls this is my hw

*plus i will give you 5 stars and if the answer is specific and clear, i will also mark you as the brainiest answer. *

To start, we know that the equation we are trying to find is a straight line. It hits the x-axis at -3 and the y-axis at -1.
Thus, we know that the line passes through (0, -1) and (-3, 0).

We can now find the gradient using the gradient form:

Thus, the gradient becomes:


Since we have a point of interest and a gradient, we can use the point-gradient form of a straight line to find the equation of the straight line.


Use either the y-intercept or the x-intercept as your point.



Thus, the equation becomes:


Now, since the shaded region is below the line, we know that the inequality becomes:



But, since it's dotted, we need to exclude the line itself.
Thus, the inequality becomes:

Yes you do, so £1973.09 - £1473.50 = £499.59 so tim overpaid £499.59 .hope this ; )
