Understanding Proportional Relationships and Slope

The video tutorial explains how to graph a proportional relationship using a table of x and y values. It demonstrates plotting points on a graph and calculating the slope by determining the change in y over the change in x. The tutorial concludes by verifying the correctness of the calculated slope.

What is the y-value when x is 3 according to the table?

• 0

• 0.5

• 1.5

• 1

Which point is used to graph the line with integer coordinates?

• (9, 1.5)

• (6, 1)

• (3, 0.5)

• (0, 0)

How many points are needed to specify a line?

• One

• Two

• Three

• Four

What is the change in y when x changes from 0 to 6?

• 0

• 1

• 1.5

• 0.5

How do you calculate the slope of a line?

• Difference between x and y

• Sum of x and y

• Change in y over change in x

• Change in x over change in y

What is the slope of the line given the change in x is 6 and change in y is 1?

• 1

• 0

• 6

• 1/6
