Understanding Slope-Intercept Form

The video tutorial explains how to graph a linear equation using the slope-intercept form, Y = MX + B. It begins by converting the equation 2X - Y = -1 into slope-intercept form by isolating Y. The slope (M) and Y-intercept (B) are identified as +2 and +1, respectively. The tutorial then demonstrates how to graph the line by plotting the Y-intercept and using the slope to find additional points. The process is summarized, and viewers are informed that another example will be covered in the next video.

What is the slope-intercept form of a linear equation?

• B = YX + M

• Y = MX + B

• Y = B + MX
