Representing Algebraic Relationships

Front

What is the origin in a coordinate plane?

Back

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

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).

Front

What does Quadrant I represent in a coordinate plane?

Back

Quadrant I is the section of the coordinate plane where both x and y values are positive.

Front

What does Quadrant II represent in a coordinate plane?

Back

Quadrant II is the section of the coordinate plane where x values are negative and y values are positive.

Front

What does Quadrant III represent in a coordinate plane?

Back

Quadrant III is the section of the coordinate plane where both x and y values are negative.

Front

What does Quadrant IV represent in a coordinate plane?

Back

Quadrant IV is the section of the coordinate plane where x values are positive and y values are negative.

Front

What is an additive relationship?

Back

An additive relationship is a relationship where a constant value is added to a variable to produce a result.

Front

How do you identify the coordinates of a point in Quadrant IV?

Back

In Quadrant IV, the x-coordinate is positive and the y-coordinate is negative.

Front

What is the value of y when x = 4 in the equation y = x - 7?

Back

When x = 4, y = 4 - 7 = -3.

Front

What is the value of y when x = 3 in the equation y = 2x + 1?

Back

When x = 3, y = 2(3) + 1 = 7.
