What does the 'm' represent in the slope-intercept form y = mx + b?
Back
The 'm' represents the slope of the line, which indicates the rate of change of y with respect to x.

FLASHCARD QUESTION
Front
What does the 'b' represent in the slope-intercept form y = mx + b?
Back
The 'b' represents the y-intercept, which is the point where the line crosses the y-axis.

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