Front

What is a function?

Back

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

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

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the value of y when x = 0.

Front

What is the solution to the system of equations? (1, -1), (-1, 1), (0, -2), (2, 0)

Back

(1, -1)

Front

How do you determine if a mapping is a function?

Back

A mapping is a function if each input is paired with exactly one output.

Front

What is scientific notation?

Back

Scientific notation is a way to express large or small numbers using powers of ten.

Front

What is the slope of the line represented by the equation y = 4x + 3?

Back

The slope is 4.

Front

What does the term 'linear equation' mean?

Back

A linear equation is an equation that makes a straight line when graphed.

Front

How do you find the y-intercept from the equation y = 0.1x + 5?
