Slope: -3
y-intercept: (0,7)
Negative 4 is less than negative 1
Answer:
A, dilation by a scale factor of 2 and a reflection across the y-axis
Step-by-step explanation:
The answer is 3,196 this is the answer because you do 3344-148=3,196
Let W = number of white cars, and Y = number of yellow cars.
There were 9 times as many white cars as yellow cars. This means that the number of white cars was 9 times more than the number of yellow cars. This can be translated by the expression:
9Y = W
The person counted 40 cars in total:
W + Y = 40
So we get the system:

In the first equation, we multiply by 9:
9W + 9Y = 360
In the second equation:
9Y= W
W-9Y = 0
Then we add the first with the second equation:
9W + 9Y + W - 9Y = 360
10 W = 360
W = 36
So He counted 36 white cars.
Hope this Helps! :)
