Front

Identify the x-intercept of the graph: What point does the graph cross the x-axis?

Back

The x-intercept is (-2, 0).

Front

What is the definition of a y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis.

Front

How do you find the x-intercept of a linear equation?

Back

Set y = 0 and solve for x.

Front

What does it mean for two lines to be parallel?

Back

Parallel lines never intersect and have the same slope.

Front

What is the solution set for the inequality x > 3?

Back

The solution set includes all numbers greater than 3.

Front

What is the graphical representation of the inequality x < 5?

Back

A line that is dashed at x = 5, shading to the left.
