Identifying Slope and Y-Intercept

Front

What is the slope of a line in the equation format y = mx + b?

Back

The slope (m) represents the rate of change of y with respect to x. It indicates how steep the line is.

Front

What does the y-intercept represent in the equation y = mx + b?

Back

The y-intercept (b) is the point where the line crosses the y-axis, indicating the value of y when x = 0.

What is the y-intercept of the equation y = 0.5x - 3?

Back

-3

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

Use the formula: m = (y2 - y1) / (x2 - x1).
