Answer:
So the slope of this function is
and the y-intercept is 
Step-by-step explanation:
A first order function has the following format:

In which a is the slope and b is the y-intercept, that is, the value of y when x = 0.
We have the following equation:

We just have to rewrite this equation



Which means that

So the slope of this function is
and the y-intercept is
