Answer:

  • 8

Step-by-step explanation:

Rate of change is the slope.

Take two ordered pairs from the table:

  • (2, 19) and (5, 43)

Find the slope:

  • m = (43 - 19) / (5 - 2) = 24 / 3 = 8

Rate of change means slope .

Take 2 points

  • (8,67)
  • (11,91)

[tex]\\ \sf\longmapsto m=\dfrac{y_1-y_1}{x_2-x_1}[/tex]

[tex]\\ \sf\longmapsto m=\dfrac{91-67}{11-8}[/tex]

[tex]\\ \sf\longmapsto m=\dfrac{24}{3}[/tex]

[tex]\\ \sf\longmapsto m=8[/tex]
