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.

How do you determine if a point lies on a line represented by an equation?

Back

Substitute the x-coordinate of the point into the equation and see if the resulting y-value matches the y-coordinate of the point.

Back

It represents the region below the line y = -2x + 4, including the line itself.

Front

How do you find the equation of a line given two points?

Back

Use the formula for slope (m) = (y2 - y1) / (x2 - x1) and then use the point-slope form to find the equation.

Front

What is a system of inequalities?

Back

A system of inequalities consists of two or more inequalities that are considered simultaneously.

Front

How do you graph a system of inequalities?

Back

Graph each inequality on the same coordinate plane and identify the region where the solutions overlap.
