Front

What is the population of Bakersfield if Los Angeles has a population of 3,800,000 and it is about 9 times larger?

Back

The population of Bakersfield is approximately 422,222.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if they intersect at a right angle (90 degrees).

Front

Which equation is parallel to y = 3/4x + 5?

Back

The equation y = 3/4x - 7 is parallel because it has the same slope (3/4).

Front

How do you find the equation of a line given a slope and a point?

Back

Use the point-slope form: y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point.

Front

Solve for x: -5x = -20

Back

x = 4.

Front

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

Back

The slope is 2.

Front

What is the slope of a line that is perpendicular to the line represented by the equation y = -3x + 1?

Back

The slope is 1/3 (the negative reciprocal of -3).

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and never intersect.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line.
