Adonis Roach · Answer 1

3x - (y/4) = 11

subsitute

in (x, y) form

if (3,-8)

subsitute 3 for x and - 8 for y

3 (3) - (-8/4) = 11

9 - (-2) = 11

9+2=11

11=11

(3,-8) is a valid soultion

try 4,4

subsittue 4 for x and 4 for y

3 (4) - (4/4) = 11

12 - (1) = 11

12-1=11

11=11

(4,4) is a valid solution

both are true so the answer choice is B, both are solutions
