Question

write correct answer​

Answer 1

Answer:

To determine graphically whether the following pair of linear equation 2x-3y=5,3x+4y=-1

has unique solution, infinity many solution,no solution.

Find the points on eq1

2x-3y=5

on putting x=-2

y=-3

(-2,-3)

on putting x=4

y=1

(4,1)

Mark these points and draw line.

Find the points on eq1

3x-4y=-1

on putting x=-3

y=2

(-3,2)

on putting x=1

y=-1

(1,-1)

Mark these points and draw line.

Both the lines are intersecting and meet at (1,-1).

Thus,have unique Solution.

Hope it helps you.
