(MCA) 3.8 Review Unit 3.

Front

What is the definition of slope in mathematics?

Back

Slope is defined as the ratio of the rise (vertical change) to the run (horizontal change) between two points on a line.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

Write the standard form of a linear equation.

Back

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

Front

What does the equation y = mx + b represent?

Back

This equation represents the slope-intercept form of a linear equation, where m is the slope and b is the y-intercept.

Front

How do you find 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 equation of a line that passes through the point (4, 9) and is horizontal?

Back

The equation of the horizontal line is y = 9.

Front

If a line has a slope of 2, what does this indicate about the line's steepness?

Back

A slope of 2 indicates that for every 1 unit the line moves horizontally, it rises 2 units vertically, making it relatively steep.

Front

What is the relationship between parallel lines in terms of slope?

Back

Parallel lines have the same slope.

Front

What is the relationship between perpendicular lines in terms of slope?

Back

Perpendicular lines have slopes that are negative reciprocals of each other.
