Understanding Linear Functions and Coordinates

The video tutorial introduces graphing concepts for 5th graders, focusing on understanding and plotting coordinates on a graph. It explains the x and y axes, how to graph points, and explores equations like y = x + 3 and y = 0.1x. The tutorial emphasizes identifying patterns and solving equations through examples and scratch work.

Why is graphing emphasized in the STAR test for 5th graders?

• It helps in understanding complex equations.

• It is not part of the test.

• It is a major part of the test.

• It is a fun activity.

What are the two forms of equations discussed in the video?

• y = ax and y = x + a

• y = x^2 and y = x - a

• y = a/x and y = x - a

• y = ax^2 and y = a + x

What do the x and y values represent in a coordinate?

• x is horizontal, y is vertical

• Both are horizontal

• x is vertical, y is horizontal

• Both are vertical

How do you plot a point using coordinates?

• Go up first, then across

• Go diagonally

• Go across first, then up

• Go randomly

Which value comes first in a coordinate pair?

• Y value

• X value

• Both at the same time

• It doesn't matter

What is the equation used to solve the first problem?

• y = 3x

• y = x + 3

• y = x/3

• y = x - 3

What is the pattern in the table for y = x + 3?

• y = x + 3

• y = x/3

• y = x - 3

• y = 3x

If x = 6, what is y in the equation y = x + 3?

• 12

• 9

• 6

• 3

Which table correctly represents y = x + 3?

• Table A

• Table D

• Table B

• Table C

What does y = 0.1x mean?

• y is 0.1 times x

• y is x divided by 10

• y is 10 times x

• y is x plus 0.1
