What is the x-intercept of the equation 3x + 8y = 24?

Back

The x-intercept is the point where the graph intersects the x-axis. For the equation 3x + 8y = 24, the x-intercept is (8, 0).

Front

What does the inequality y > 2x - 4 represent graphically?

Back

The inequality y > 2x - 4 represents the region above the line y = 2x - 4 on a graph.

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers.

Front

How do you factor the quadratic expression x^2 + 24x + 144?

Back

The expression factors to (x + 12)^2.

Front

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

Back

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

Front

What is the definition of a system of inequalities?

Back

A system of inequalities is a set of two or more inequalities with the same variables.

Front

How do you find the y-intercept of the equation 6x - 4y = 24?

Back

To find the y-intercept, set x = 0 and solve for y. The y-intercept is (0, -6).

Front

What does it mean for a function to be linear?

Back

A function is linear if it can be represented by a straight line on a graph, typically in the form y = mx + b.

Front

What is the process for solving a system of equations graphically?

Back

To solve a system of equations graphically, plot both equations on the same graph and identify the point(s) where they intersect.
