These linear functions are in the form: y = ax + b

Plugging in any value of x will give you the value of y, and vice-versa.

The grid says that when x = 0, y = 1.35. And also, when x = 22.5, y = 0.

So you can eliminate half of the possibilities by plugging x = 0 in all the equations.

When x = 0, y = ax + b is simply y = b. So only A. and B. make sense so far.

When y = 0, y = ax + b is simplifies to 0 = ax + b which simplifies to ax = -b. By plugging x = 22.5, you should be able to deduce which of the answers is right. I can confirm if you'd like

An inequality can be formed by simply translating the problem statement to numerical expressions.

From the problem we know that 3w added with 52 hours should be equal or greater than 90 (helpful insight from the keyword "at least"). Therefore, it's inequality would look like:

3w+52>=90 (>= is used instead of ≥ for constraints in formatting)

The inequality above best models the situation.
