Verified Answer
How many points are in the interior of the region enclosed by x 0, y 0...
x - 2y = -8 is a line with x-intercept = -8 andy-intercept = 4.
We need to consider the interior of region enclosed by x-axis, y-axis and line x - 2y = -8. -8 < x < 0 and 0 < y < 4. When y = l , x - 2 > - 8 i.e., 0 > x > - 6. x = -1, -2, -3, -4, -5 Similarly, if y = 2, x = - 1 , - 2 , - 3 and if y = 3, x = -1 Hence the required number of points = 5 + 3 + 1= 9 Hence, option 5.
