FLASHCARD QUESTION

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, usually represented as 'm'. It is calculated as the ratio of the change in y-values to the change in x-values between two points on the line.

2.

FLASHCARD QUESTION

Front

How do you find the y-intercept of a linear equation?

Back

The y-intercept of a linear equation is the value of y when x is 0. It can be found by substituting x = 0 into the equation.

3.

FLASHCARD QUESTION

Front

What does the equation y = mx + b represent?

Back

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

4.

FLASHCARD QUESTION

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope (m) but different y-intercepts (b).

5.

FLASHCARD QUESTION

Front

What is the formula for calculating slope between two points (x1, y1) and (x2, y2)?

Back

The formula for slope (m) is: m = (y2 - y1) / (x2 - x1).

6.

FLASHCARD QUESTION

Front

What is the significance of a slope of 0?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.

7.

FLASHCARD QUESTION

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, resulting in a line that slopes downward from left to right.
