If you subtract x from each side, it says Y = -x .
That tells you that the slope of the graph is -1, and the y-intercept is zero.

The graph is a straight line, passing through the origin.
It slopes DOWN from left to right, at an angle of 45 degrees.

Suppose you Just purchased a used truck. The number of miles on the odometer can be represented by the equation y = x + 40, 000,

igor_vitrenko [27]

Answer: $f(x)= x+40000$

Step-by-step explanation:

We write a function f(x) which gives the values of the function that are dependent on the independent variable "x".

Given: The number of miles on the odometer can be represented by the equation y = x + 40, 000, where y is the number of miles on the odometer, and x is the number of miles you have driven it.

Here y is dependent on x, so we replace y by f(x), then we get

$f(x)= x+40000$ which is the required answer.
