Question 31588: My friend is driving 55mph West and he started from his home which is 75 miles West of mine. I leave at the same time, traveling West at the speed of 73 mph. Write 2 linear equations (one for me and one for my friend) that relate our distances away from my home versus time.

Hello!
The distance of your friend can be written as:

where t is time in hours. At t=0 (when he was at his home), he was 75 miles from your home (this checks using the above equation). Then, for each hour that passes, he will be 55 miles further away from your home. Hence the above equation.
Your distance from your homes (I'm assuming you started from your home) is:

At t=0, you were at 0 miles from your home (you were at home). Then, for each hour that passes, you will be 73 miles further away. Hence that equation.

I hope this helps!
