Question

A snack box contains at most 7 ounces of cheese. Fiona says the amount of cheese can be represented by 2x - 3. Which graph shows the possible answer? Please help!

Answer 1

The function representing the number of ounces is:
2x - 3
Now, we are given the number of ounces = 7
Therefore:
2x - 3 = 7
We will solve this equation for x as follows:
2x-3 = 7
2x = 7 + 3
2x = 10
x = 5

Therefore, the number line representing this function will be the line having a solution ending at 5 (5 is included).

Therefore, the correct choice would be line B
