Question

If the coordinates of two points are $P(-2,3)$ and $Q(-3,5)$, then $(abscissaofP-abscissaofQ)$ is :

• A. $-5$
• B. $1$
• C. $-1$
• D. $-2$

Answer 1

The correct option is B

$1$

Step : Determine the value of $(abscissaofP-abscissaofQ)$

Given the coordinates of two points are $P(-2,3)$ and $Q(-3,5)$.

We know that, the abscissa of a point is its x co-ordinate.

Therefore, the abscissa of point $P=-2$ and the abscissa of point $Q=-3$.

Now,

$$\begin{gathered} (abscissaofP-abscissaofQ)=-2-(-3) \\ =-2+3 \\ =1 \end{gathered}$$

Hence the correct answer is option B.
