Question

Mr. Bigelow's garden is a rectangle with dimensions x feet long by y feet wide. It's perimeter is 70 feet.

a. Write a function to represent the perimeter of his garden?
b. What are the x- and y- intercepts of the function?
c. Does either intercept make sense as a solution for this situation? Explain.

Answer 1

a) 2x + 2y = 70

b) y-intercept is 35.
x-intercept is 35.

c) No, because at each intercept, the other coordinate is 0. You cannot have a length of 0 when referring to s rectangular garden (this would be a straight line).

i.e. (35,0) and (0,35)
