Front

What type of slope does a horizontal line have?

Back

Zero

Front

Which of these sets is not a function? { (2,3) , (2,5) , (4, 9) }

Back

Front

What is the definition of a rational number?

Back

A rational number is any number that can be expressed as a fraction a/b, where a and b are integers and b is not zero.

Front

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

Back

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

Front

What does it mean for a slope to be undefined?

Back

A slope is undefined when the line is vertical.
