check to see whether
7 = (7/5)(5)
what do you think?
Consider the point (5,7) which lies on line l in the coordinate plane. Could y=7/5x represent line l?

It's 7=7. So it does represent line l, right?
you are correct.
consider the point p (-2,1) and the line l: x+y=2
find slope of l
find slope of l
