1 ) 2x - 3 y = 5
2 ) 3 x + 4y = - 1
I just need the points to plot on graph !!!

1.) y- 1 3 5
x- 4 7 10
2.) y- 2 4 -1
x- (-3) (-5) 1
x- 4 7 10
2.) y- 2 4 -1
x- (-3) (-5) 1

You need to determine whether the straight lines given, do intersect each other or not ? and at which point ?
2x - 3y = 5 => y = (2x-5) / 3
x -5 -2 0 1 3 4 7 10
y -5 -3 -5/3 -1 1/3 1 3 5
================================
3 x + 4y = -1 => x = (- 1 - 4y) /3
y -5.5 -4 -2.5 -2 -1 0 2 5 8
x 7 5 3 7/3 1 -1/3 -3 -7 -11
2x - 3y = 5 => y = (2x-5) / 3
x -5 -2 0 1 3 4 7 10
y -5 -3 -5/3 -1 1/3 1 3 5
================================
3 x + 4y = -1 => x = (- 1 - 4y) /3
y -5.5 -4 -2.5 -2 -1 0 2 5 8
x 7 5 3 7/3 1 -1/3 -3 -7 -11
