Minus p both sides
xy=5-p
divide both sides by x
y=(5-p)/x
B
Answer: Choice C) y = 2x
The line goes through the origin, so the y intercept is b = 0
The slope is rise/run = 2/1 = 2 because we go up 2 units for every unit we go to the right. This is why m = 2.
Plug m = 2 and b = 0 into the slope intercept form to go from y = mx+b to y = 2x+0, which is the same as y = 2x.
Temporarily subdivide the given area into two parts: a large rectangle and a parallelogram. Find the areas of these two shapes separately and then combine them for the total area of the figure.
By counting squares on the graph, we see that the longest side of the rectangle is the hypotenuse of a triangle whose legs are 8 and 2. Applying the Pyth. Thm., we find that this length is √(8^2+2^2), or √68. Similarly, we find the the width of this rectangle is √(17). Thus, the area of the rectangle is √(17*68), or 34 square units.
This leaves the area of the parallelogram to be found. The length of one of the longer sides of the parallelogram is 6 and the width of the parallelogram is 1. Thus, the area of the parallelogram is A = 6(1) = 6 square units.
The total area of the given figure is then 34+6, or 40, square units.
