World problems need help?

Question

Ok so I have a lot of math homework and there are something I am not getting.

1. I have a problem that says points A,B, and C are three vertices of a rectangle. Plot the three points. (a) find the coordination of the fourth point, D, to complete the rectangle. (b) Find the area of the rectangle; use A=lw. Than gives me problems A(-4,2), B(7,2), C(7,8).

Than I have one where I have to graph p= 15n-300 for n ≤ 60.

Not looking for answers just need to know what steps I am suppose to take.

1.  To be a rectangle the point has to have the same x value as point A.  So that's x=-4 and it has to have the same y value as C y=8, so D is (-4,8)

l= 7 - (-4) = 11
w = (8-2) = 6

A=11*6=66

p = 15n - 300 is the equation of a straight line with p being the vertical axis and n the horizontal axis.

Draw the line for a the point n=0, p=300, and n=60, p=600, with two points you can draw a line that ends at the point (60,600), passes through (0,300) and continues indefinitely for all values < 0.

So fourth point  D is  (-4,8)
then length is 11 and width is 6
Area  =66
