What is a linear function?

A linear function is a mathematical function where the graph of the function forms a straight line when plotted on a graph. It can be represented by the equation f(x) = mx + b, where m is the slope of the line and b is the y-intercept. Linear functions have a constant rate of change and have a direct relationship between the independent variable x and the dependent variable f(x).

How do you represent a linear function mathematically?

A linear function is represented mathematically in the form of f(x) = mx + b, where m is the slope of the line and b is the y-intercept. This equation describes a straight line graph where the output (y) is directly proportional to the input (x). The slope determines how steep the line is, while the y-intercept indicates where the line crosses the y-axis.

What are the key characteristics of a linear function?

A linear function is a mathematical relationship that can be represented by a straight line on a graph. Its key characteristics include having a constant rate of change, meaning that the slope of the line is always the same, and having a y-intercept, which is the point where the line intersects the y-axis. Linear functions can be expressed in the form y = mx + b, where y represents the output, x represents the input, m is the slope, and b is the y-intercept.

How do you determine the slope of a linear function?

To determine the slope of a linear function, you can first identify two points on the graph of the function and then use the formula for slope, which is (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. The slope represents the rate at which the function is increasing or decreasing along the y-axis for every unit change on the x-axis.

How do you find the y-intercept of a linear function?

To find the y-intercept of a linear function, set x=0 in the equation of the linear function and solve for y. The y-coordinate where the function intersects the y-axis is the y-intercept.

What is the slope-intercept form of a linear function?

The slope-intercept form of a linear function is y = mx + b, where y represents the output variable, x is the input variable, m is the slope of the line, and b is the y-intercept of the line where the graph intersects the y-axis.

How do you graph a linear function?

To graph a linear function, begin by identifying the y-intercept (where the line crosses the y-axis) and the slope (change in y divided by change in x) of the function. Plot the y-intercept on the y-axis, then use the slope to determine additional points on the line. Connect these points to create a straight line that extends infinitely in both directions.

What is the relationship between the slope of a linear function and its graph?

The slope of a linear function is directly related to the steepness of the graph of the function. The slope measures the rate at which the function is increasing or decreasing. A positive slope indicates a function that is increasing, while a negative slope indicates a function that is decreasing. The larger the absolute value of the slope, the steeper the graph will appear.

How can you determine if two linear functions are parallel?

Two linear functions are parallel if they have the same slope. To determine if two linear functions are parallel, compare the coefficients of the x term in their equations. If the coefficients are the same, then the two linear functions are parallel. If the coefficients are different, then the lines are not parallel.

How can you determine if two linear functions are perpendicular?

Two linear functions are perpendicular if the product of their slopes is equal to -1. In other words, if one function has a slope of m1 and the other has a slope of m2, they are perpendicular if and only if m1 * m2 = -1. This is a key property of perpendicular lines in the Cartesian plane.
