Chapter 9, Problem 29RE

To determine

To find: The expression of $P=\left(1,-2\right)$ ; $Q=\left(3,-6\right)$ .

Answer to Problem 29RE

The expressions can we written as $\frac{1}{2}=0.5$ .

Explanation of Solution

Given information:

The given expression,

  $P=\left(1,-2\right)$ ; $Q=\left(3,-6\right)$

Calculation:

Calculate the decimal equivalent of the friction $\frac{1}{2}=0.5$

The expressions on both the sides are the same. So, both the points are on the same location on a real number line.

If a point is at the same location point $b$ on a number line, then $a=b$ .

Therefore, the expression given can be written as $\frac{1}{2}=0.5$
