How do you compare two linear functions?
Compare two linear functions
- Identify the rate of change for the first function, .
- Identify the rate of change for the second function, .

- Compare the properties of each function.
What information can be used to compare linear relationships?
A linear relationship can be represented by a straight-line graph and by an equation of the form y=mx+b. In the equation, m is the slope of the line, and b is the y-intercept. Used to track changes over short and long periods of time. When smaller changes exist, this graph is better to use than bar graphs.
How can linear equations help you compare linear functions?
While all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value).
What does it mean to compare linear functions?
Linear functions can be represented in words or as equations, graphs, or tables. • To compare linear functions, determine the rate of change and intercepts of each function. • Review the following processes for identifying the rate of change and y-intercept of a linear function.
How do you compare linear functions on a graph?
Linear functions can be represented in words or as equations, graphs, or tables. To compare linear functions, determine the rate of change and intercepts of each function. Review the following processes for identifying the rate of change and y-intercept of a linear function.
How do I find the rate of change?
To find the average rate of change, divide the change in y-values by the change in x-values.
How do we rewrite slope-intercept form to standard form or vice versa?
To convert from slope intercept form y = mx + b to standard form Ax + By + C = 0, let m = A/B, collect all terms on the left side of the equation and multiply by the denominator B to get rid of the fraction.
What is an example of a comparison problem?
Difference Unknown: One type of compare problem involves finding out how many more are in one set than another. For example, James has 6 mice. Joy has 11 mice. How many more mice does Joy have than James?
How do you compare two mathematical equations?
The comparison method, a procedure for solving systems of independent equations, starts by rewriting each equation with the same variable as the subject. Any of the variables may be chosen as the first variable to isolate. Each equation is now an isolated-subject equation, and equation where one variable is isolated.
