linear equations using 12 and 16 college credits

Question

upon admitted to berkeley you were credited with 12 credits from your previous institution and you have decided to take 16 credits per quarter in order to meet the graduation requirements for your degree in two years

Answer 1

Roger, draw a graph with the quarter numbers going along the bottom and the credits going up the side. I would go by 4's up the side (4, 8, 12...).

 

You are starting with 12 credits, so you should have a dot on your y-axis at 12, because you have gone 0 quarters and have 12 credits.

 

Now, at quarter 1, how many credits will you have if you take 16? 28, so put a dot at (1,28).

 

Keep going. Your dots should all end in a straight line.
