Coordinate Plane-1st Quadrant

Front

What is the coordinate plane?

Back

A two-dimensional surface where points are defined by a pair of numbers (x, y).

Front

What does the first quadrant of the coordinate plane represent?

Back

The first quadrant is where both x and y values are positive.

Front

How do you write an ordered pair?

Back

An ordered pair is written as (X, Y), where X is the horizontal value and Y is the vertical value.

Front

What is the origin in the coordinate plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on the coordinate plane.

Front

What is the y-axis?

Back

The y-axis is the vertical line on the coordinate plane.

Front

How do you identify a point on the coordinate plane?

Back

A point is identified by its coordinates (x, y), where x is the distance from the y-axis and y is the distance from the x-axis.

Front

What is the distance from the origin to the point (3, 4)?

Back

The distance is 5 units, calculated using the Pythagorean theorem: √(3² + 4²) = 5.

Front

What is the slope of a line?

Back

The slope is a measure of how steep a line is, calculated as the change in y divided by the change in x.

Front

What does the equation y = mx + b represent?

Back

This is the slope-intercept form of a linear equation, where m is the slope and b is the y-intercept.
