Question

How do you write linear equations in function notation?

Answer 1

First, convert the linear equation to slope-intercept form. The slope-intercept form of a linear equation is: `y = color(red)(m)x + color(blue)(b)`

Where `color(red)(m)` is the slope and `color(blue)(b)` is the y-intercept value.

Then switch out the `y` variable for `f(x)`:

`f(x) = mx + b`
