Finding the Y-Intercept from a Table

The video tutorial explains how to find the y-intercept (b) when x is not zero. It begins by labeling variables and setting up the slope formula. The slope is calculated, and then used in the slope-intercept form equation. An ordered pair is substituted into the equation to solve for b. Finally, the video derives the final equation with the calculated slope and y-intercept.

What is the first step in finding the slope?

• Simplifying the equation

• Labeling the points as x1, y1, x2, y2

• Finding the y-intercept

• Substituting values into the slope formula

Which points are labeled as x1 and y1?

• The last point in the table

• Any random point

• The first point in the table

• The second point in the table

What is the formula for the slope (m)?

• (x1 - x2) / (y1 - y2)

• (y1 - y2) / (x1 - x2)

• (x2 - x1) / (y2 - y1)

• (y2 - y1) / (x2 - x1)
