Question
Slope and Rate of Change A linear function is given. (a) Sketch the graph. (b) Find the slope of the graph. (c) Find the rate of change of the function.
$$
f(x)=2 x-6
$$
Instant Answer
Step 1
The general form of a linear function is $f(x)=mx+b$, where $m$ is the slope and $b$ is the y-intercept. Comparing this with the given function, we can see that the slope $m=2$ and the y-intercept $b=-6$. Show more…
