1. Which line is the flattest (or is less steep)? Why?
y = 5x 6
y = 5x + 6
y = x  3
y = x + 3
I think it's the last one!
Parallel lines have the same slope. The first two are parallel lines with the steepest slope; the last two are parallel lines as well and would both fit the answer to your question.

y=x+3
