SOLUTION: Hi tutor, I need help on this problem. It is asking me to graph the these lines and highlight the positive slope lines pink and the negative blue. So how would you gr

y = 3x + 5 

The slope is the coefficient of x, which is 3 when the equation of the line is
solved for y.  It is positive so I colored it pink

Here is the line:




y = 0.5x + 3 

That one has slope 0.5, which is also positive.  

Here is its graph:



Lines that go uphill to the right like this / have positive slopes.  
Lines that go downhill to the right like this \ have negative slopes.
