Midterm Review 1 & 3

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

What is the distance formula in a coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).

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

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

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

Back

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

Front

What is the relationship between complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

How do you determine the slope of a line perpendicular to a given line?

Back

The slope of a line perpendicular to another is the negative reciprocal of the original line's slope.

Front

What is the process to convert an equation from standard form to slope-intercept form?

Back

Solve for y to isolate it on one side of the equation.

Front

If m∠K + m∠L = 90°, what can you say about angles K and L?

Back

Angles K and L are complementary.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis (x=0).
