How much has the value of y changed between the points (-8, 4) and (8, -4)?

Solution:

Given, two points are (-8, 4) and (8, -4).

We have to find the change in value of y.

We know that

Change in the value of y = 4 - (-4) = 8 units

Therefore, the change in value of y is 8 units.

Example:

How much has the value of y changed between the points (-2, 6) and (2, -6)?

Solution:

Given, two points are (-2, 6) and (2, -6).

We have to find the change in value of y.

We know that

Change in the value of y = 6 - (-6) = 12 units

Therefore, the change in value of y is 12 units.

How much has the value of y changed between the points (-8, 4) and (8, -4)?

Summary:

The change in value of y between the points (-8,4) and (8, -4) is 8 units.
