type the 5 - letter code in order of the problems (1 - 5) in the answer box. do not use spaces.

Explanation:

Step1: Slope formula for table 1

Slope formula: $m=\frac{y_2-y_1}{x_2-x_1}$
Use points $(-3,-13)$ and $(-1,-7)$:
$m=\frac{-7-(-13)}{-1-(-3)}=\frac{6}{2}=3$
Match to letter I.

Step2: Slope formula for table 2

Use points $(0,6)$ and $(3,5)$:
$m=\frac{5-6}{3-0}=-\frac{1}{3}$
Match to letter A.

Step3: Slope formula for table 3

Use points $(-4,11)$ and $(-1,-1)$:
$m=\frac{-1-11}{-1-(-4)}=\frac{-12}{3}=-4$
Match to letter D.

Step4: Slope formula for table 4

Use points $(-3,5)$ and $(3,5)$:
$m=\frac{5-5}{3-(-3)}=\frac{0}{6}=0$
Match to letter G.

Step5: Slope formula for table 5

Use points $(-1,-7)$ and $(2,-1)$:
$m=\frac{-1-(-7)}{2-(-1)}=\frac{6}{3}=2$
Match to letter H.
