We have a linear function $\displaystyle\bf y=\underbrace{k}_{gradient}x+b$ and we know that $\displaystyle\bf \left \{ {{-2\cdot-3+b=2} \atop {-4\cdot -2+b=k}} \right. => \left \{ {{b=-4} \atop {b+8=k} \right. => k=8-4=4 \\\\Answer: \boxed{B) \quad k=4}$

To determine if (1, 2 ) is a solution of the inequality, substitute the coordinates into the inequality and if satisfied then they are a solution, that is

(6 × 1) - 2 = 6 - 2 = 4 > 3

Since 4 > 3 then (1, 2 ) is a solution
