Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output for each input.

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.

Front

How do you determine if a relation is a function?

Back

A relation is a function if every input has exactly one output.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

What is the slope of the line represented by the equation y = 3x + 5?

Back

The slope is 3.

Front

What is the y-intercept in the equation y = -2x + 4?

Back

The y-intercept is 4.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What does the inequality x < -1 represent on a number line?

Back

It represents all numbers to the left of -1, not including -1.

Front

What is the graphical representation of y = -x + 2?

Back

It is a straight line with a slope of -1 and a y-intercept of 2.

Front

What is the meaning of the term 'slope'?

Back

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