Answer:

  • 0.6

Step-by-step explanation:

The rate of change is the ratio of Δy/Δx, where Δ means the difference between consecutive values.

We name it the slope:

  • [tex]m = (y_2-y_1)/(x_2-x_1)[/tex]

Use two pairs of x and y values and find the slope:

  • [tex]m = (-85.8 - (-87))/(2 - 0) = 1.2/2 = 0.6[/tex]

Points are

  • (0,-87)
  • (2,-85.8)
  • (4,-84.6)
  • (6,-83.4)

Take 2nd and third points

[tex]\\ \sf\longmapsto m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\\ \sf\longmapsto m=\dfrac{-84.6+85.8}{4-2}[/tex]

[tex]\\ \sf\longmapsto m=\dfrac{1.2}{2}[/tex]

[tex]\\ \sf\longmapsto m=0.6[/tex]
