5) Two straight roads diverge at an angle of
65 degrees. Two cars leave the
intersection at 2:00 PM, one traveling at
50 mi/h and the other at 30 mi/h. How far
apart are the cars at 2:30 PM?

Given the graph below state whether or not the relation is a function, and give the domain and range.

X-intercept=-5 y-intercept=2 the equation of the line is
