- Y = 1/2X + 4 ( Equation – 1)
- Y = –5/4X – 3 ( Equation – 2)
Here, Y = 1/2X + 4
Or, –5/4X – 3 = 1/2X + 4 (From equation 1 and 2)
Or, –5/4X = 1/2X + 4 + 3
Or, –5/4X = 1/2X + 7
Or, 1/2X + 7 = –5/4X
Or, 7 = –5/4 X – 1/2 X
Or, –5/4X – 2/4 X = 7
Or, –7/4 X = 7
Or, –7 X = 7 × 4
Or, –7X = 28
Or, X = 28/–7
Or, X = – 4
Here, in the fourth option, we can see that X= –4, Hence Option D— (-4,2) Is correct.
