Slope and Y-intercept

Front

What is the slope in the equation y = mx + b?

Back

The slope (m) represents the rate of change of y with respect to x.

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.

Front

Determine the slope from the equation y = 3x + 2.

Back

Slope: 3

Front

Determine the y-intercept from the equation y = -4x + 1.

Back

Y-intercept: (0, 1)

Front

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

Back

Slope = (y2 - y1) / (x2 - x1)
