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)

You have two equations.

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

Second equation:
x <= y
Turn x<=y to x = y and plot

Now you have to plot this and then use a test point to see which is true for both equations. The image is what it will look like after you plot. Your answer would be your third picture.
