Calculating Slope and Graph Points

The video tutorial explains how to find the slope of a graph. It begins by introducing the concept of slope and the need to select two points on the graph. The tutorial then explains the slope formula, labels the points, and demonstrates how to plug the values into the formula to calculate the slope. The final result shows that the slope of the line is 2.

What is the first step in finding the slope of a graph?

• Calculate the distance between points

• Draw a line through the points

• Find the midpoint of the line

• Identify two points on the graph

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

• M = (X2 - X1) / (Y2 - Y1)

• M = (Y2 - Y1) / (X2 - X1)

• M = (Y1 - Y2) / (X1 - X2)

• M = (X1 + X2) / (Y1 + Y2)

Why is it important to label the points when calculating the slope?

• To ensure the points are in the correct order

• To make the graph look neat

• To avoid confusion with other graphs

• To help in drawing the line

If the points on a graph are (2, 3) and (4, 7), what is the slope of the line?

• 3

• 4

• 2

• 1

What is the result of dividing the difference in Y-values by the difference in X-values for the points (2, 3) and (4, 7)?

• 1

• 4

• 3

• 2
