What is the slope of LaTeX: f\left(x\right)=3x-1

arlik [135]

To find the slope of the expression:

$f(x)=y=3x-1$

We need to remember that this is the Slope-intercept Form of the line equation:

$y=mx+b$

Where

m = slope

b is the y-intercept.

Therefore, the slope of the line equation above is m = 3.
