Finding Slope from Tables and Points

The video tutorial explains how to find the slope from a table and using two points. It begins with an introduction to the concept of slope, followed by a detailed explanation of finding slope from a table by calculating the change in y over the change in x. The tutorial then introduces the slope formula for two points, demonstrating how to use it with examples. Key points include reducing fractions and ensuring the slope remains a fraction, not a decimal.

What is the first step in finding the slope from a table?

• Find the change in x over the change in y

• Find the change in y over the change in x

• Add the x values

• Subtract the y values

If the change in y is -5 and the change in x is 10, what is the slope?

• -2

• 2

• -0.5

• 0.5

What should you do with the fraction representing the slope?

• Convert it to a decimal

• Reduce it to the lowest terms

• Leave it as it is

• Multiply it by 10

What is the slope formula for two points?

• m = Y2 - Y1 / X2 - X1

• m = X2 - X1 / Y2 - Y1

• m = Y1 - Y2 / X1 - X2

• m = X1 - X2 / Y1 - Y2

In the slope formula, what does Y2 represent?

• The second y-coordinate

• The first x-coordinate

• The second x-coordinate

• The first y-coordinate

When using the slope formula, what should you do if you are subtracting a negative number?

• Divide the numbers

• Multiply the numbers

• Subtract the numbers

• Add the numbers

What is the slope if Y2 = 8, Y1 = 2, X2 = 15, and X1 = 5?

• -0.5

• 0.5

• -2

• 2

If you have two points (-20, 12) and (-3, 7), what is the slope?

• 16/5

• 32/10

• 5/16

• 10/32

What happens when you divide two negative numbers?

• The result is zero

• The result is negative

• The result is undefined

• The result is positive

What should you always remember about the slope in terms of its format?

• It must be a decimal

• It must be a fraction

• It must be an integer

• It must be a whole number
