Graphing Proportional Relationships

The video tutorial introduces graphing proportional relationships, starting with the equation y=2x. It explains how to create a table of x and y values, plot ordered pairs on a graph, and understand the significance of graph quadrants. The tutorial concludes with graphing another proportional relationship, y=3/4x, demonstrating the process of creating a table and plotting points to form a straight line.

What is the equation used to represent the proportional relationship in the video?

• y = 2x

• y = x + 2

• y = x - 2

• y = 2/x

If x is 1 in the equation y = 2x, what is the value of y?

• 1

• 2

• 3

• 4

What are the ordered pairs for the values x = 0, 1, 2, 3, and 4 in the equation y = 2x?

• (0,0), (1,1), (2,2), (3,3), (4,4)

• (0,0), (1,2), (2,4), (3,6), (4,8)

• (0,2), (1,4), (2,6), (3,8), (4,10)

• (0,1), (1,3), (2,5), (3,7), (4,9)

Which quadrant is used for graphing proportional relationships?

• First quadrant

• Second quadrant

• Third quadrant

• Fourth quadrant

What is the ordered pair for the point where x = -5 and y = 3?

• (5, -3)

• (-5, 3)

• (5, 3)

• (-5, -3)

What is the new equation introduced in the video?

• y = x + 3/4

• y = 2x

• y = 3/4x

• y = 4/3x

If x is 4 in the equation y = 3/4x, what is the value of y?

• 1

• 4

• 3

• 2

What are the ordered pairs for the values x = 0, 4, and 8 in the equation y = 3/4x?

• (0,3), (4,6), (8,9)

• (0,0), (4,3), (8,6)

• (0,1), (4,2), (8,3)

• (0,0), (4,4), (8,8)

What is the value of y when x is 8 in the equation y = 3/4x?

• 7

• 6

• 5

• 4

What is the process to graph a proportional relationship?
