Question

The point (2.5, 1) is also on the line. What is the vertical change between (2.5, 1) and (5, 2)? What is the horizontal change?

Answer 1

Answer:

In a general point (x, y) the horizontal component is the x-component, and the vertical component is the y-component.

then if we have the points (a, b) and (c, d)

The vertical distance or change between these points will be the difference between the y-components, and the horizontal distance or change is the difference between the x-components.

Then the vertical change between the points (2.5 , 1) and (5, 2) is:

2 - 1 = 1 unit.

The horizontal change between the points (2.5, 1) and (5, 2) is:

5 - 2.5 = 2.5 units.
