FLASHCARD QUESTION
Front
What is the slope of a line?
Back
The slope of a line is a measure of its steepness, typically represented as 'm' in the slope-intercept form of a linear equation (y = mx + b). It is calculated as the change in y divided by the change in x (rise/run).

FLASHCARD QUESTION
Front
What is the slope-intercept form of a linear equation?
Back
The slope-intercept form of a linear equation is given by the formula y = mx + b, where 'm' is the slope and 'b' is the y-intercept.

FLASHCARD QUESTION
Front
How do you find the slope between two points (x1, y1) and (x2, y2)?
Back
The slope (m) between two points is calculated using the formula m = (y2 - y1) / (x2 - x1).

FLASHCARD QUESTION
Front
What is the y-intercept of a line?
Back
The y-intercept of a line is the point where the line crosses the y-axis, represented as 'b' in the slope-intercept form (y = mx + b).

FLASHCARD QUESTION
Front
How do you convert the standard form of a linear equation to slope-intercept form?
Back
To convert from standard form (Ax + By = C) to slope-intercept form (y = mx + b), solve for y to isolate it on one side of the equation.

FLASHCARD QUESTION
Front
What is the standard form of a linear equation?
Back
The standard form of a linear equation is expressed as Ax + By = C, where A, B, and C are integers, and A should be non-negative.

FLASHCARD QUESTION
Front
What does it mean for two lines to be parallel?
Back
Two lines are parallel if they have the same slope but different y-intercepts, meaning they will never intersect.
