## What are the characteristics of a linear equation?

A linear equation in two variables can be described as a linear relationship between x and y, that is, two variables in which the value of one of them (usually y) depends on the value of the other one (usually x). In this case, x is the independent variable, and y depends on it, so y is called the dependent variable.

## How do you describe nonlinear equations?

A system of nonlinear equations is a system of two or more equations in two or more variables containing at least one equation that is not linear. We solve one equation for one variable and then substitute the result into the second equation to solve for another variable, and so on.

## What common characteristics do equations have?

In mathematics, equation define as a statement that the values of two mathematical expressions are equal, it was indicated by the equal sign (=). It is also a process of equating one into another. Non-linear equation, has a term in square, cubic or raise to the power of any number greater than 3.

## How do you write a linear function?

To write a linear function, you need two pieces of information: the slope and the y-intercept. Once you have determined these two variables, you can substitute them in for m and b in the slope-intercept form y=mx+b.

## What is an example of a nonlinear function?

An example of a nonlinear function is y = x^2. This is nonlinear because, although it is a polynomial, its highest exponent is 2, not 1.

## How can you determine if an equation is linear equation in two variables?

If a, b, and r are real numbers (and if a and b are not both equal to 0) then ax+by = r is called a linear equation in two variables. (The “two variables” are the x and the y.) The numbers a and b are called the coefficients of the equation ax+by = r.

## How do you describe graphs?

Adverbs: dramatically, rapidly, hugely, massive, sharply, steeply, considerably, substantially, significantly, slightly, minimally, markedly. There is also a list of adverbs to describe the speed of a change: rapidly, quickly, swiftly, suddenly, steadily, gradually, slowly.

## What are features of a graph?

Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.

## What are the key components of a graph?

CARMALT – Basic parts of graphs

5 components of a good graph are: TITLE, AXES, INCREMENTS, LABELS, SCALE
tells what graph is about TITLE
changing variable is known as _____ INDEPENDENT
Dependent variable is on which axis that is vertical? Y

## What is the difference between linear and nonlinear functions?

Linear FunctionA linear function is a relation between two variables that produces a straight line when graphed. Non-Linear FunctionA non-linear function is a function that does not form a line when graphed.

## How do you describe a linear?

A linear relationship (or linear association) is a statistical term used to describe a straight-line relationship between two variables. Linear relationships can be expressed either in a graphical format or as a mathematical equation of the form y = mx + b.

## What is one characteristic of all linear functions?

A linear function has a constant rate of change. A rate of change is the difference in the dependent variable for every change in the independent variable. This means it has equal differences over equal intervals.

## What are the key features of exponential functions?

Properties of exponential function and its graph when the base is between 0 and 1 are given.

• The graph passes through the point (0,1)
• The domain is all real numbers.
• The range is y>0.
• The graph is decreasing.
• The graph is asymptotic to the x-axis as x approaches positive infinity.

## What are the qualities of a function?

A function is a relation in which each possible input value leads to exactly one output value. We say “the output is a function of the input.” The input values make up the domain, and the output values make up the range.
