Question

Consider the points (−4, 0) and (5, 0).

a. What do the ordered pairs have in common, and what does that mean about their location in the coordinate plane?
b. How did we find the distance between two numbers on the number line?
c. Use the same method to find the distance between (−4, 0) and (5, 0).

Answer 1

answered

Explanation:

A) there y- coordinates are same . This means that the points lie on the x- axis only.

b) since the y- coordinate is zero of both the points. The distance between them must be same as the distance between their x- coordinates. Which can be easily obtained with help of the number line. Here the distance will be equal to 9 units.

c) since the y- coordinate is zero of both the points. The distance between them must be same as the distance between their x- coordinates. Which can be easily obtained with help of the number line. Here the distance will be equal to 9 units
