Finding the Slope from Tables and Ordered Pairs

This video tutorial explains how to find the slope using the slope formula, which is crucial for high school math. It covers finding the slope between two points using the formula y2 - y1 divided by x2 - x1, both with and without graphs. The tutorial also demonstrates how to find the slope from a table of values, emphasizing the importance of labeling points and handling negative numbers. Practical examples are provided to reinforce understanding.

What is the formula for finding the slope between two points?

• y2 + y1 / x2 + x1

• y2 - y1 / x2 - x1

• x2 - x1 / y2 - y1

• x1 - x2 / y1 - y2

Why is it important to note the subtraction signs in the slope formula?

• Because they change the order of operations

• Because they can be ignored

• Because they ensure correct calculation of rise and run

• Because they indicate the direction of the slope

What is the slope of the line passing through the points (0, 2) and (4, 7)?

• 5/4

• 2/7

• 4/5

• 7/2

When using the slope formula, what should you do if you encounter negative values?

• Ignore the negative signs

• Multiply the values

• Add the values instead of subtracting

• Treat the subtraction of a negative as addition

What is the slope between the points (9, 7) and (5, 12)?

• 2/7

• 7/2

• -2/7

• -7/2

How do you handle the subtraction of negative numbers in the slope formula?

• Subtract them as usual

• Ignore the negative signs

• Multiply the numbers

• Treat it as addition

What is the slope of the line passing through the points (3, 0) and (6.5, 7.25)?

• 4

• -4

• 3

• -3

How do you find the slope from a table of values?

• By adding all the values

• By choosing any two points and using the slope formula

• By counting the rise and run

• By multiplying the x and y values

What is the slope of the table with points (1, -3) and (-1, 0)?

• -1.5

• 1.5

• -3

• 3

If a table shows the amount of money remaining on a gift card based on the number of drinks purchased, what does a slope of -1.75 indicate?

• Each drink adds $1.75 less to the gift card

• Each drink adds $1.75 to the gift card

• Each drink costs $1.75 less than the previous one

• Each drink costs $1.75
