![a.
Why are the lines whose equations are y=x+4 and y=-2x-3 perpendicular?
b. Use a graphing utility to graph the equations in a [-10,10,1] by [-10,10,1] viewing rectangle. Do the lines appear to be perpendicular?
c. Now use the zoom square feature of your utility. Describe what happens to the graphs. Explain why this is so.
a. Choose the correct answer below.
A. The product of their slopes is 1.

Do the lines appear to be perpendicular in this viewing window?
Yes
No
O C.
c. Choose the correct answer below.
Q
A. The lines now appear to be less perpendicular than before because this new viewing window shows more of the two graphs.
B. Nothing changes because the functions themselves have not changed.
O C. The lines now appear to be perpendicular because in this new viewing window, the distances between tick marks on the x-
and y-axes are equal.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F746c528c-1bb1-4b60-ba79-65bd8df817d1%2Ffc0368f3-8015-4eee-b678-1308a44b51f2%2Fbqws6zw_processed.png&w=3840&q=75)
