The Cartesian Plane

Question 1

Cartesian Plane

Answer 1

A two-dimensional plane where the x-axis is the horizontal axis and the y-axis is the vertical axis.

Question 2

Quadrant

Answer 2

In the Cartesian Plane, the two axes divide the plane into four sections called quadrants. The quadrants are numbered staring with the upper-right section as quadrant I. Then moving counterclockwise, quadrant II is the upper-left section, quadrant III is the lower-left section, and quadrant IV is the lower-right section.

Question 3

Ordered Pairs

Answer 3

A n ordered pair, represented as (x, y), corresponds to a point on the Cartesian Plane. The x-coordinate represents the horizontal distance the point is from the origin and the y-coordinate represents the vertical distance the point is from the origin.

Question 4

Equation in Two Variables

Answer 4

An equation that contains two separate variables (generally, x and y).

Question 5

Intercepts

Answer 5

The points where the graph of an equation crosses (or touches) the axes of the Cartesian Plane are known as intercepts.
The x-intercept is the point where the graph of the equation crosses the x-axis. (The y-coordinate of an x-intercept is zero.)
The y-intercept is the point where the graph of the equation crosses the y-axis. (The x-coordinate of a y-intercept is zero.)

Question 6

Numbered Quadrants

Answer 6

Quadrants are number counter clockwise, or in the shape of a C. (starting with one ending in 4)

Question 7

How To:

Answer 7

1) Create T-chart
2) Enter values into a column in chart, use positive and negative values
3) Sub each value for a variable to calculate for the other variable
4) Plot ordered pairs
5) Connect points or plot more points until shape is known
