How can I solve these types of question
Which of the following pairs of coordinates corresponds to a point in the shaded region of the graph shown above? Answer = A
(Please find figure attached)
a) (9, −7)
b) (−9, −7)
c) (9, 7)
d) (7, −9)
e) (−7, −9)
Two points..
(I) Shaded region is in the quadrant where x>0 and y<0..
so only (9,-7) and (7,-9) are left.
Now the line passes through (10,10) and (0,0), so all points on line have x=y..
the slope is lesser in the shaded region, that is above the line.. Here the value of y should be lesser than the numeric value of x without the sign..
So |9|>|-7| so A
