During last night’s basketball game, Lisa Schmidt made 30 points in field goals. A field goal is worth 2 or 3 points.

Question

If Lisa made 9 field goals worth 2 points each, how many did she make worth 3 points each?
Let x represent the number of 2-point field goals Lisa made and
y represent the number of 3-point field goals she made. Write an
equation to model the situation.
Plot several points to graph the equation.
Where does the line cross the x-axis? What does this point
represent in terms of Lisa’s points?
Where does the line cross the y-axis? What does this point
represent in terms of Lisa’s points?

Answer 1

x=9
2x+3y = 30

Now the rest of the questions get easier.
