Unit 9 Review - Algebraic Representations

Front

What is an ordered pair in a coordinate system?

Back

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

Front

What does the x-coordinate represent in an ordered pair?

Back

The x-coordinate represents the horizontal position of a point on the coordinate grid.

Front

What does the y-coordinate represent in an ordered pair?

Back

The y-coordinate represents the vertical position of a point on the coordinate grid.

Front

In which quadrant is the point (-3, 1.5) located?

Back

Quadrant II, because x is negative and y is positive.

Front

What are dependent and independent quantities in a graph?

Back

Independent quantities are the input values (x), while dependent quantities are the output values (y) that depend on the input.

Front

If Ram walks at a speed of 3 miles per hour, how far will he walk in 2 hours?

Back

He will walk 6 miles, calculated as speed × time = 3 miles/hour × 2 hours.

Front

What is the equation of a line that has a slope of 3 and passes through the origin?

Back

The equation is y = 3x.

Front

What is the definition of a coordinate grid?

Back

A coordinate grid is a two-dimensional plane formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What is the significance of the origin in a coordinate system?

Back

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

Front

How do you identify the quadrant of a point with negative x and positive y coordinates?

Back

It is located in Quadrant II.
