For similar triangles, the side lengths are proportional. So, you can write a proportion relating the two pairs of vertical and
horizontal side lengths. For the line y = 2x, a triangle can be drawn 2 units up and 1 unit right from the origin.
Write a proportion relating the side lengths of the triangle to any other triangle that has the line as a hypotenuse, a horizontal length of x units, and a vertical length of y units.

Answer:
They charged <u>$6</u> for washing and <u>$2</u> for vacuuming the car.
Step-by-step explanation:
Let the charge of washing a car be 'x'.
And also let the charge of vacuuming a car be 'y'.
Now according to question, Trisha raised $38 washing 5 cars and vacuuming 4 cars.
So framing the above sentence in equation form, we get;
Again according to question, Byron raises $28 by washing 4 cars and vacuuming 2 cars.
So framing the above sentence in equation form, we get;
Now multiplying equation 2 by '2', we get;
Now we subtract equation 1 from equation 3 and get;
Now substituting the value of 'x' in equation 1, we get;
Hence They charged <u>$6</u> for washing and <u>$2</u> for vacuuming the car.
