Question : If we look closely at computer screen, we see that the screen is made up of millions of tiny squares called pixels. Number of pixels together form a digital image on screen every clickable point represents x-co-ordinates as number of pixels along horizontal axis i.e., x-axis and y co-ordinate as number of pixels along vertical axis i.e. y-axis.

Find

i) What is the perpendicular distance of A (165, 250) from x axis. [1 Marks]

ii) In which quadrant the abscissa of a point is negative. [1 Marks]

iii) What is the sum of abscissa of A and B. [2 Marks] 

Doubt Question by Purvi 

Solution : 
(i) 250 units.
(ii) II and III Quadrant 

(iii) 
A(165, 250) 

B(300, 250)

Sum of abscissa of A and B
=165+300
= 465
