Finding Slope from Points and Graphs

The video tutorial explains how to find slopes from graph points and tables. It introduces the concept of slope as a rate of change, recaps the slope formula, and demonstrates its application through multiple example problems. The tutorial emphasizes the importance of labeling points and writing the formula for accuracy. It concludes with a brief mention of using tables for slope calculations.

What is the definition of slope in terms of rate of change?

• Change in x over change in y

• Difference between x and y changes

• Sum of x and y changes

• Change in y over change in x

What is the first step in calculating the slope from two points?

• Label the points

• Subtract the y-values

• Write the formula

• Subtract the x-values

In the formula Y2 - Y1 / X2 - X1, what does Y2 represent?

• The y-coordinate of the first point

• The x-coordinate of the first point

• The y-coordinate of the second point

• The x-coordinate of the second point

How can the slope be represented if the calculation gives 8 over -3?

• 8 over 3

• -8 over 3

• It goes upwards

• It is horizontal

• It is vertical

What should you do if you misplace one number in the slope formula?

• Use a different method

• Recalculate the slope

• Ignore the mistake

• Change the formula
