FLASHCARD QUESTION
Front
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 y-intercept from the equation y = -2x + 5?
Back
The y-intercept is the value of y when x = 0. In the equation y = -2x + 5, the y-intercept is 5.

FLASHCARD QUESTION
Front
What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?
Back
The formula to calculate the slope (m) between two points is m = (y2 - y1) / (x2 - x1).

FLASHCARD QUESTION
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 increase in x, the value of y increases by 2 units, making the line steep.
6.
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.
7.
FLASHCARD QUESTION
Front
What is the slope of the line that passes through the points (2, 4) and (6, 12)?
Back
The slope is 2, calculated using the formula m = (12 - 4) / (6 - 2).
