B. y = 84

Step-by-step explanation:

see the below

$when \: \frac{y}{x} = \frac{24}{2}$

then

24/2=12/1 then,

$\frac{y}{x = 7} = \frac{12 \times 7}{7}$

$\longrightarrow \frac{y = 84}{x = 7}$

hence options b is correct

(–3, 3) then 3 <2(-3) +3 3 < - 3 FALSE
(–2, –2) then -2 <2(-2)+3 -2 < -1 TRUE
(–1, 1) then 1 <2(-1) +3 1 < 1 FALSE
(0, 1) then 1 <2(0) + 3 1 < 3 TRUE
(2, 5) then 5 <2(2)+3 5< 7 TRUE

answer
(–2, –2)
(0, 1)
(2, 5)
