SOLUTION: A waiter earns $10 in tips plus $5 per hour. This is represented by the function y=10+5x. What happens to the graph of the line if the waiter earns $5 per hour but only $3 in tips?

You can put this solution on YOUR website!
the equation of the first line is y = 5x + 10
the equation of the second line is y = 5x + 3
the second equation is parallel to the first equation because the slope is the same.
the total value of the second line will always be 7 less than the total value of the first line.
for example:
when x = 5, y1 = 35 and y2 = 28 for a difference of 35 - 28 = 7
when x = 50, y1 = 260 and y2 = 253 for a difference of 260-253 = 7
this is because the amount of tips are assumed to be fixed at 10 and 3.
this is not realistic, but it's the way the problem was posed.
