Explanation:

Step1: Recall slope formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$.

Step2: Calculate slope for 1st case

For the graph in 1, if we take two - points $(0,0)$ and $(1,2)$, then $m=\frac{2 - 0}{1 - 0}=2$ (corresponds to C).

Step3: Calculate slope for 2nd case

For the table in 2, using two points $(0,7)$ and $(1,4)$, $m=\frac{4 - 7}{1 - 0}=-3$ (corresponds to A).

Step4: Calculate slope for 3rd case

For the points $(2,18)$ and $(4,28)$ in 3, $m=\frac{28 - 18}{4 - 2}=\frac{10}{2}=5$ (corresponds to H).

Step5: Calculate slope for 4th case

For the graph in 4, if we take two - points $(0,0)$ and $(1,1)$, then $m=\frac{1 - 0}{1 - 0}=1$ (corresponds to F).
