Question

A middle school club is planning a homecoming dance to raise money for the school. Decorations for the dance cost $80, and the club is charging $10 per student that attends.

Which graph describes the relationship between the amount of money raised (y) and the number of students who attend the dance (x)?

Group of answer choices

graph with the x axis labeled number of students and the y axis labeled amount of money raised and a line going from the point 0 comma negative 80 through the point 2 comma negative 60

graph with the x axis labeled number of students and the y axis labeled amount of money raised and a line going from the point 0 comma negative 80 through the point 2 comma negative 100

graph with the x axis labeled number of students and the y axis labeled amount of money raised and a line going from the point 0 comma 80 through the point 2 comma 60

Answer 1

The first graph.

Reason: y = 10x − 80 (ticket income minus the $80 cost). So y(0) = −80 and y(2) = 20 − 80 = −60, matching the line through (0, −80) and (2, −60).
