What is the difference between Discrete and Continuous data?

Back

Discrete data consists of distinct, separate values (e.g., number of students), while Continuous data can take any value within a range (e.g., height, weight).

Front

What does it mean for a system of equations to have infinitely many solutions?

Back

It means that the equations represent the same line, and every point on that line is a solution.

Front

How can you determine if a point is a solution to a system of equations?

Back

Substitute the point's coordinates into both equations. If both equations are true, the point is a solution.

Front

What does it mean for two lines to be parallel in a system of equations?

Back

Parallel lines have the same slope but different y-intercepts, meaning they never intersect and have no solutions.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is greater than, less than, or not equal to the other.

Front

How do you graph a linear inequality?

Back

Graph the corresponding linear equation as a solid line (if ≤ or ≥) or dashed line (if < or >) and shade the region that satisfies the inequality.

Front

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

Back

Front

Back

The y-intercept is 3, which is the point where the line crosses the y-axis.

Front

What does it mean for a system of equations to have no solution?

Back

It means that the equations represent parallel lines that never intersect.
