30 for 4 cars
15+15+15+15 = 30
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:Points: (2,15), (8,60)slope = m = rate of change m = [change in y-coordinate] / [change in x-coordinate]m = [60 - 15] / [8 - 2] = 45 / 6 = 7.5
The point - slope form of the equation of the line is:y - y₁ = m (x - x₁)
Using the point (x₁, y₁) = (2, 15), you get:y - 15 = 7.5 (x - 2)
Then, to find how much Drew charges for 4 cars, substiture x = 4:y - 15 = 7.5 (4 - 2)
Solving:y = 7.5(2) + 15 = 15 + 15 = 30
Thus, the answer is that Drew charges $ 30 for 4 cars.
i dont know the values but im think you can multiply the value of 222 cars by 2 to get the value of 444 cars i believe please mark brainliest if im correct
