Mr. McKay wrote an algebra test with a total of 15 questions consisting of multiple choice and short response style questions. Multiple choice questions,
X, were worth 5 points each and short response questions, y, were worth 10
points each. There were 100 total possible points on the test. Write and graph
a system of linear equations for this situation to determine the number of
each type of question.
