Drew earns money washing cars for his neighbors on the weekends. drew charges a set rate for each car he washes.
the points on the following coordinate plane show how much drew charges for 2, 5, and 8 cars.

how much does drew charge for 4 cars?

Explanation:

The three points on the coordinate plane lie on a line. Then, they can be represented by a linear function restricted to the domain of the natural numbers.

To write the linear function you just need to use two points. Using the points trhat represent the money earned from washing 2 and 8 cars you get:

The point - slope form of the equation of the line is:

Using the point (x₁, y₁) = (2, 15), you get:

Then, to find how much Drew charges for 4 cars, substiture x = 4:

Solving:

Thus, the answer is that Drew charges $ 30 for 4 cars.
