Question

Tom has $10 that he wants to use to buy pens and pencils. However, he does not want to buy more pens than pencils. A pen costs $3, and a pencil costs $1. Which graph represents this scenario? (Here, x represents the number of pens and y the number of pencils.)

A)
B)
C)
D)
E)

Answer 1

You have two equations.

First equation:
3x + y = 10 <---plot
