What is the y-intercept of a linear function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis. It is represented as (0, b) where b is the value of the y-intercept.

Front

How do you find the zero of a linear function?

Back

The zero of a linear function is found by setting the function equal to zero and solving for x. It represents the x-value where the graph crosses the x-axis.

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

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x. It indicates how steep the line is.

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. Solutions to the system are the points where the graphs of the equations intersect.

What does it mean if a system of equations has no solution?

Back

A system of equations has no solution if the graphs of the equations are parallel and never intersect.

How do you determine the rate of change from a table of values?

Back

The rate of change can be determined by finding the difference in the y-values divided by the difference in the x-values between two points.

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

What is the significance of the x-intercept in a linear function?

Back

The x-intercept is the point where the graph crosses the x-axis, represented as (a, 0) where a is the x-intercept value.

Front

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form y = mx + b.
