## What is a linear function word problem?

Word problems sometimes ask us to write a linear function to model a situation. The word problem may be phrased in such a way that we can easily find a linear function using the slope-intercept form of the equation for a line. Example 1: So, the y -intercept is 15 . The rate of change is 0.11 .

## How do you create a linear equation?

Use a line already drawn on a graph and its demonstrated points before creating a linear equation. Follow this formula in making slope-intercept linear equations: y = mx + b. Determine the value of m, which is the slope (rise over run). Find the slope by finding any two points on a line.

## What is the equation of linear function?

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

## How do you solve problems involving linear functions?

To solve a linear function, you would be given the value of f(x) and be asked to find x.Solving Linear FunctionsSubstitute the value of f(x) into the problem. 8=3x-1.Isolate the variable. Continue to isolate the variable. Simplify.
