Are y = 2x + 4 and y=1/2x + 4 perpendicular or just intersecting? Explain.
They are intersecting and not perpendicular because slopes are different, but not opposite reciprocals.

Is (2, -1) a solution to the system:
y = 4x − 9
y = x − 3?
Explain your answer in a complete sentence and show your work.
Yes, it is a solution to the system of equations because if you substitute (2, -1) for x and y, it makes both equations true.

There were 300 people at a play. The admission price was $3 for adults and $1 for children. The admission receipts were $700.
Alton says that 200 adults and 150 children attended the play. Explain 2 reasons why he is incorrect.
More than 350 people
Also would be 3(200) + 150 = $750 in receipts, not $700.
