Determining Negative Slope from a Table of Values

The video tutorial explains how to calculate the slope of a line using a table of values. It emphasizes that the values do not need to be consecutive and demonstrates the process of selecting two points to find the change in y-coordinates over the change in x-coordinates. The tutorial provides a detailed example calculation, highlighting the importance of understanding the difference between values to determine the slope, which is -2 in the given example.

What is the main concept introduced in the beginning of the video?

• Finding the y-intercept

• Calculating the slope

• Solving quadratic equations

• Determining the x-intercept

What do we need to determine the slope from a table?

• The sum of all values

• All values in the table

• Two values from the table

• The average of all values

Which of the following is NOT necessary when picking values to determine the slope?

• Values must be next to each other

• Values can be different

• Values do not need to be consecutive

• Values can be any two points

What values are chosen to calculate the slope in the video?

• 5 and 7

• 2 and 4

• 3 and 5

• 1 and 2

What is the change in y-coordinates between the chosen values?

• 3

• 4

• 5

• 2

How do you find the change between two values?

• Subtract the smaller value from the larger value

• Subtract one value from the other

• Multiply the two values

• Add the two values

What is the result of -9 minus 5?

• -14

• -4

• -2

• -10

What is the change in x-coordinates between the chosen values?

• 4

• 3
