## What are some real life examples of linear functions?

For example, after you’ve watered your plants, you might wish to keep track of how much each one has grown. The amount of water you give a plant determines how much it grows. The letter y denotes the dependent variable in a linear equation.

### How do you solve a linear function problem?

Solving Linear Functions

- Substitute the value of f(x) into the problem. In this case:
- Isolate the variable. In this case, you add 1 to both sides to isolate the variable term by using the opposite operation to move the constant term across the equal sign.
- Continue to isolate the variable.
- Simplify.

#### How do you solve problems involving linear functions?

**What is a linear function in math?**

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.

**How can you apply linear equations in your day to day life?**

Applications of Linear Equations in Real life

- It can be used to solve age related problems.
- It is used to calculate speed, distance and time of a moving object.
- Geometry related problems can be solved.
- It is used to calculate money and percentage related problems.
- Work, time and wages problems can be solved.

## In what real life situation can you apply the concept of solving linear inequalities?

A system of linear inequalities is often used to determine the best solution to a problem. This solution could be as simple as determining how many of a product should be produced to maximize a profit or as complicated as determining the correct combination of drugs to give a patient.

### What is real life problem solving?

Real-Life Problem Solving: A Collaborative Approach to Interdisciplinary Learning describes an approach to interdisciplinary learning in which students and teachers investigate open-ended, authentic problems that have clear relevance both to themselves and to the larger community.

#### How do u find a linear function?

Linear functions are typically written in the form f(x) = ax + b. The a represents the gradient of the line, which gives the rate of change of the dependent variable. This is also known as the “slope.” The b represents the y-axis intercept.

**How do you know if a word problem is linear?**

To clue you in, linear equation word problems usually involve some sort of rate of change, or steady increase (or decrease) based on a single variable. If you see the word rate, or even “per” or “each”, it’s a safe bet that a word problem is calling for a linear equation.

**How do I find a linear function?**

A linear function is represented by the equation y = mx + b where:

- y is the y-coordinate.
- m is the slope of the line, or how steep it is.
- x is the x-coordinate.
- b is the y-intercept, or where the line crosses the y-axis on a graph.

## What are some real world problems?

They are:

- Climate Change.
- Health Care.
- Food Insecurity.
- Violence.
- Homelessness.
