For (-3, 4)

(a) 2x + y = 6

LHS = 2(- 3) + 4

= -6 + 4 = -2

-2 6

(b) y = 2x + 4

4 = 2(-3) + 4

4 -6 + 4

(c) 2 (x - 1) + 3y = 4

2(-3-1) + 3(4) = 4

2(-4) + 12 = 4

-8 + 12 = 4

4 = 4

(d) 2x - 3y = 6

2(-3) -3(4) 6

Since, (-3, 4) is solution of 2(x-1) + 3y = 4

Given graph is of equation 2 (x - 1) + 3y = 4
