6.11A Graphing 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 graph points, lines, and curves.

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, identify the x-coordinate and y-coordinate, then move right from the origin (0,0) for the x-value and up for the y-value.

Front

What does the point (3, 4) represent?

Back

The point (3, 4) represents a location in the first quadrant where you move 3 units to the right (x = 3) and 4 units up (y = 4) from the origin.

Front

What is the significance of the origin in the coordinate plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect. It serves as the reference point for all other points in the coordinate plane.

Front

How do you identify the coordinates of a point?

Back

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

Front

What is the difference between positive and negative coordinates?

Back

Positive coordinates indicate a position to the right (x) or above (y) the origin, while negative coordinates indicate a position to the left (x) or below (y) the origin.

Front

How do you plot a point in the second quadrant?

Back

To plot a point in the second quadrant, move left from the origin for the x-coordinate (which is negative) and up for the y-coordinate (which is positive).

Front

What does the point (-2, 5) represent?

Back

The point (-2, 5) represents a location in the second quadrant where you move 2 units to the left (x = -2) and 5 units up (y = 5) from the origin.

Front

How do you plot a point in the third quadrant?

Back

To plot a point in the third quadrant, move left from the origin for the x-coordinate (which is negative) and down for the y-coordinate (which is also negative).
