6.11A Graphig Points in All Four Quadrants

Front

What is the coordinate plane?

Back

The coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). It is used to locate points using ordered pairs (x, y).

Front

What are the four quadrants of the coordinate plane?

Back

The four quadrants are: 1st Quadrant (x > 0, y > 0), 2nd Quadrant (x < 0, y > 0), 3rd Quadrant (x < 0, y < 0), 4th Quadrant (x > 0, y < 0).

Front

How do you plot a point in the first quadrant?

Back

To plot a point in the first quadrant, take the x-coordinate and move right from the origin, then take the y-coordinate and move up. For example, the point (3, 2) is plotted by moving 3 units right and 2 units up.

Front

What does the ordered pair (0, 0) represent?

Back

The ordered pair (0, 0) represents the origin of the coordinate plane, where the x-axis and y-axis intersect.

Front

How do you identify the coordinates of a point?

Back

The coordinates of a point are identified as an ordered pair (x, y), where 'x' is the horizontal distance from the origin and 'y' is the vertical distance from the origin.

Front

What is the significance of the x-axis and y-axis?

Back

The x-axis is the horizontal line on the coordinate plane, and the y-axis is the vertical line. Together, they help in locating points and defining the quadrants.

Front

How do you plot a point in the second quadrant?

Back

To plot a point in the second quadrant, take the x-coordinate (which is negative) and move left from the origin, then take the y-coordinate (which is positive) and move up. For example, the point (-2, 3) is plotted by moving 2 units left and 3 units up.

Front

What is the formula to find the distance between two points (x1, y1) and (x2, y2)?

Back

The distance formula is: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What does it mean if a point has a negative x-coordinate?

Back

A negative x-coordinate means the point is located to the left of the origin on the x-axis.

Front

What does it mean if a point has a negative y-coordinate?

Back

A negative y-coordinate means the point is located below the origin on the y-axis.
