I WILL RATE POSITIVE.
a. Why are the lines whose equations are y = x+5 and y = - 4x - 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? a c. Now use the zoom square feature of your utility. Describe what happens to the graphs. Explain why this is so. C a. Choose the correct answer below. O A. Their y-intercepts have opposite signs. O B. They intersect at exactly one point. OC. The product of their slopes is 1. OD. The product of their slopes is - 1
b. Choose the correct graph below. OA. OB. Ос. OD. Q Q
Do the lines appear to be perpendicular in this viewing window? 0 Yes O No c. Choose the correct answer below. O A. 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. OB. The lines now appear to be less perpendicular than before because this new viewing window shows more of the two graphs. O C. Nothing changes because the functions themselves have not changed.
