An inequality is a mathematical statement that compares two expressions using symbols such as <, >, ≤, or ≥.

Front

What does the symbol '≥' mean?

Back

'≥' means 'greater than or equal to'.

Front

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

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

Front

What is the y-intercept of the equation y = -4x - 5?

Back

The y-intercept is -5.

Front

What is a function?

Back

A function is a relation where each input has exactly one output.

Front

Which of the following is not a function: A, B, C, D?

Back

B is not a function.

Back

x = -1.

Front

What does it mean for a graph to represent y ≥ 2x - 2?

Back

It means the graph includes all points above the line y = 2x - 2, including the line itself.

Front

How do you graph the inequality y < 2x - 2?

Back

Graph the line y = 2x - 2 as a dashed line and shade below it.

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.
