GEOMETRY: Chapter 3 REVIEW

Front

What does the equation x = 2 represent in a graph?

Back

A vertical line that crosses the x-axis at the point (2, 0).

Front

What is the slope of a line that is perpendicular to the line represented by the equation y = \frac{1}{2}x + 2.3?

Back

-2

Front

Write the equation of a line that is PARALLEL to y = 2x + 3 and passes through the point (3, 1).

Back

y = 2x - 5

Front

Write the equation of a line that passes through the point (7, 10) and is PERPENDICULAR to the line y = \frac{1}{2}x - 9.

Back

y = -2x + 24

Front

What is the name of the angle relationship between angle 1 and angle 3 if they are on the same side of the transversal and in corresponding positions?

Back

Corresponding Angles

Front

Define 'slope' in the context of a linear equation.

Back

The slope is a measure of the steepness of a line, calculated as the rise over run (change in y over change in x).

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = \frac{y2 - y1}{x2 - x1}.

Front

What is the relationship between the slopes of two perpendicular lines?

Back

The product of their slopes is -1.

Front

What is the equation of a horizontal line?

Back

y = b, where b is the y-coordinate of any point on the line.
