Review for Unit 5 Test

Front

Calculate the area of a rectangle with vertices at (0,0), (0,4), (3,4), and (3,0).

Back

The area of a rectangle is calculated using the formula: Area = length × width. Here, length = 3 and width = 4, so Area = 3 × 4 = 12.

Front

Are the two linear equations parallel, perpendicular, or neither?

Back

Two lines are perpendicular if the product of their slopes is -1. If one line has a slope of m1 and the other has a slope of m2, then m1 * m2 = -1 indicates they are perpendicular.

Front

What is the slope of the line y=-2?

Back

The slope of a horizontal line (like y = -2) is 0.

Front

How is finding the length of segment AB written in the distance formula?

Back

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

Front

What is the distance formula used for?

Back

The distance formula is used to calculate the distance between two points in a coordinate plane.

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

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

Back

The slope-intercept form is given by: y = mx + b, where m is the slope and b is the y-intercept.
