Question 2:

Obviously the right equation for this question is Point Slope Form.

Point Slope Form: y - y1 = m(x - x1)

y1 = -1

x1 = 3

m = 2

Question 2 Answer: y + 1 = 2(x - 3)

----------------------------------

Question 3:

Again use point slope form.

Find Slope:

7 - 1 = 6

-2 - 1 = -3

6/-3 = -2

Question 3 Answer: y - 1 = -2(x - 1)

----------------------------------

Hope This Helps :)

So one way of drawing it is to draw a rectangle with area 128 ft^2 and attaching a square to one of its side.  The square that is attached has a side lenght of "s."
