and this question to please:

9.   Is (5, 17) a solution of the equation y = 4x + 3?

yes
no

For problem 12, distribute the 3 on the right side.  Then rearrange to get all x on the left side and numbers on the right.  If the result has no x left, is the remaining equation true or false?  If true, there are infinitely many solutions.  If false, there are no solutions.  Otherwise, you have a value for x, hopefully 0 or 8 :-)

For problem 12, plug x = 5 into the formula.  Do you get y = 17?  If so, it is a solution, else it is not.
