Question

Show graphically that each one of the following systems of equations is in-consistent (i.e. has no solution):
3x – 4y – 1 = 0
2x – (8/3)y + 5 = 0

Answer 1

Answer:

sorry it is tough as I'm in junior class..........

I can't solve it.......

Answer 2

There are no common points

Step-by-step explanation:

Given linear equations are  

3x – 4y = 1 ---- (1)

2x – (8/3)y = -5 ---- (2)

The above linear equations cannot be solved algebraically.

Co-ordinates for equation 1 will be (0, -1/4), (1, -1/2), (2, +5/4), (3, 2).

Co-ordinates for equation 2 will be (0, 15/8), (1, 21/8), (2, 18/8), (3, 33/8).

We find that the two lines when plotted on the graph will never intersect. There are no common points. So there are in-consistent. Hence there is no solution.
