# The equation of the line with slope -3/2 and which is concurrent with the lines 4x + 3y – 7 = 0 and 8x + 5y – 1 = 0 isA. 3x + 2y – 63 = 0B. 3x + 2y – 2 = 0C. 2y – 3x – 2 = 0D. none of these

Given:

4x + 3y 7 = 0 … (1)

8x + 5y 1 = 0 … (2)

The equation of the line with slope – 3/2 is given below:

y = - 32x + c

32x + y - c = 0 … (3)

The lines (1), (2) and (3) are concurrent.    8c = 8

c = 1

On substituting c = 1 in , we get: 3x + 2y – 2 = 0
