Explanation:

Step1: Calculate slope for Q1

Pick two points on the line, e.g., $(0,-3)$ and $(2,3)$. Use slope formula $m=\frac{y_2-y_1}{x_2-x_1}$.
$m=\frac{3-(-3)}{2-0}=\frac{6}{2}=3$

Step2: Calculate slope for Q2

Use two table points, e.g., $(0,7)$ and $(1,4)$.
$m=\frac{4-7}{1-0}=\frac{-3}{1}=-3$

Step3: Calculate slope for Q3

Use points $(2,18)$ and $(4,28)$.
$m=\frac{28-18}{4-2}=\frac{10}{2}=5$

Step4: Calculate slope for Q4

Pick two points on the line, e.g., $(0,-2)$ and $(2,-1)$.
$m=\frac{-1-(-2)}{2-0}=\frac{1}{2}$

Step5: Match slopes to choices

Q1=3 (D), Q2=-3 (A), Q3=5 (H), Q4=$\frac{1}{2}$ (B)
