Understanding Linear Functions and Patterns

The video tutorial introduces numerical patterns, focusing on additive patterns. It explains pattern rules, which are equations relating two variables, and demonstrates how to create a table using a specific rule. The tutorial then guides viewers on graphing the pattern by plotting points from the table. The video features a character, Grumpy Kitty, who interacts with the teacher to clarify concepts and provide examples.

What is an additive pattern?

• A pattern where numbers are added.

• A pattern where numbers are divided.

• A pattern where numbers are subtracted.

• A pattern where numbers are multiplied.

What do pattern rules do?

• They are used for subtraction.

• They create random numbers.

• They relate two variables.

• They only work with one variable.

In the rule y = x + 2, what does the '+2' signify?

• Subtract 2 from x.

• Multiply x by 2.

• Add 2 to x.

• Divide x by 2.

If x is 3, what is y according to the rule y = x + 2?

• 5

• 6

• 3

• 4

How do you find the y-coordinate on a graph?

• By looking at the diagonal line.

• By looking at the vertical line.

• By looking at the horizontal line.

• By looking at the circular line.

What is the y-coordinate if the x-coordinate is 4 using the rule y = x + 2?

• 5

• 6

• 7

• 8

Which point would you plot for x = 5 using the rule y = x + 2?

• (5, 9)

• (5, 6)

• (5, 7)

• (5, 8)

What is the next y-coordinate if the x-coordinate is 6?

• 7

• 8

• 10

• 9

If x is 8, what is y using the rule y = x + 2?

• 10

• 11

• 12

• 9

What is the pattern rule used in the video?

• y = x + 2

• y = x / 2

• y = x * 2

• y = x - 2
