The video tutorial explains how to find the slope of a line passing through two points. It introduces the slope formula, m = (y2 - y1) / (x2 - x1), and demonstrates its application using the points (5, 4) and (8, 6). The tutorial walks through the calculation step-by-step, showing how to subtract the y-values and x-values, and then simplify the result to find the slope, which is 2/3.

What is the first step in finding the slope of a line given two points?

• Graph the line on a coordinate plane.

• Calculate the midpoint of the line.

• Identify the coordinates of the two points.

• Find the distance between the two points.

Which of the following is the correct formula for calculating the slope of a line?

• m = (x2 + x1) / (y2 + y1)

• m = (x2 - x1) / (y2 - y1)

• m = (y2 + y1) / (x2 + x1)

• m = (y2 - y1) / (x2 - x1)

In the slope formula m = (y2 - y1) / (x2 - x1), what do y2 and y1 represent?

• The x-coordinates of the points

• The slope of the line

• The midpoint of the line

• The y-coordinates of the points
