Chapter 4 Test Review

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x, indicating how steep the line is.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

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

Back

The slope of the line is 3.

Front

What is the y-intercept in the equation y = 4x + 5?

Back

The y-intercept is 5.

Front

What is the equation of a line that passes through the point (0, 1) with a slope of 2?

Back

The equation is y = 2x + 1.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

If a line has a slope of -1, what does this indicate about its direction?

Back

A slope of -1 indicates that the line decreases as it moves from left to right.

Front

What is the equation of a line that is perpendicular to y = 2x + 3?

Back

The equation of a line perpendicular to y = 2x + 3 will have a slope of -1/2.
