Graphing and Writing Linear Equations Chapter Review

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a graph, written in the form (X,Y).

Front

How do you identify the y-intercept on a graph?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0,Y).

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, resulting in an upward slant from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, resulting in a downward slant from left to right.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line where the x-value does not change, resulting in no defined slope.

Front

What does a zero slope indicate?

Back

A zero slope indicates a horizontal line where the y-value does not change, resulting in no rise over run.

Front

How do you write the equation of a line in slope-intercept form?

Back

The slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope of the line represented by the equation y = 3x + 2?

Back

The slope (m) of the line is 3.

Front

What is the y-intercept of the line represented by the equation y = -2x + 5?

Back

The y-intercept (b) of the line is 5.

Front

How do you convert the equation 2x + 3y = 6 into slope-intercept form?

Back

To convert, solve for y: y = -rac{2}{3}x + 2.
