Coordinate Plane and Linear Equations Flashcard

Front

What is an ordered pair?

Back

A set of numbers used to locate a point on the coordinate plane.

Front

What does the x-coordinate represent in an ordered pair?

Back

The horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent in an ordered pair?

Back

The vertical position of a point on the coordinate plane.

Front

In which quadrant are both x and y coordinates positive?

Back

Quadrant I.

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

How do you determine if an ordered pair is a solution to a linear equation?

Back

Substitute the x and y values into the equation and check if the equation holds true.

Front

What is the slope of a line?

Back

The ratio of the rise (change in y) to the run (change in x) between two points on the line.
