Question
Solve y < 2 graphically.
✓
Answer
Graph of y = 2 is given in the figure
Line y = 2 divides XY-plane in two half. plane I and plane $\parallel$ Let us select a point, (0, 0) in lower half-plane I and putting y = 0 in the given inequality, we see that
1 × 0 < 2 or 0 < 2 which is true.
Thus, the solution region is the shaded region below the line y = 2.
Hence, every point below the line (excluding all the points on the line) determines the solution of the given inequality.
