Front

What is the equation of a line in slope-intercept form?

Back

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

Front

In the ordered pair (x,y), what does y represent?

Back

The y-coordinate, which indicates the vertical position on a graph.

Front

How do you solve for m in the equation m - n = 5?

Back

m = 5 + n.

Front

What does the inequality -2 ≥ n represent on a number line?

Back

All numbers less than or equal to -2.

Front

What is the solution to the equation 4x - 8 = -2(-2x + 4)?

Back

Infinitely many solutions.

Front

What is a variable in algebra?

Back

A symbol, often a letter, that represents an unknown value.

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows that one expression is greater or less than another.

Front

What does it mean for an equation to have no solutions?

Back

It means there is no value that can satisfy the equation.

Front

What is the slope of a line?

Back

The slope is a measure of the steepness of the line, calculated as the rise over run.

Front

What is the y-intercept of a line?

Back

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