Understanding Slope and Y-Intercept

The video tutorial explains how to find the slope from the equation y = 1 - 8x. It begins with a review of the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept. The tutorial clarifies that the slope is the coefficient of x, emphasizing that it is important to identify the correct number next to x. In the given equation, the slope is -8, not 1, as it is the number directly associated with x.

What is the equation given in the video for finding the slope?

• y = 8x - 1

• y = 1 + 8x

• y = -8x + 1

• y = 1 - 8x

What does the 'm' represent in the slope-intercept form y = mx + b?
