Answer 1

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