FLASHCARD QUESTION
Front
What is the equation of a linear function?
Back
A linear function can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.
2.
FLASHCARD QUESTION
Front
What does the slope of a line represent?
Back
The slope of a line represents the rate of change of y with respect to x, indicating how steep the line is.
3.
FLASHCARD QUESTION
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).

What is the slope of the line y = 3x + 5?
Back
The slope is 3.

FLASHCARD QUESTION
Front
How do you write an equation of a line parallel to y = mx + b?
Back
A parallel line will have the same slope (m) but a different y-intercept (b).
