Answer:

-.033557047

Step-by-step explanation:

Slope = (y2-y1)/ (x2-x1)

    = (4.2 - 5.6)/(.86- 40.86)

 = -1.4/ (.86 + 40.86)

= -1.4/41.72

The formula of a slope:

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

We have the points (-40.86, 5.6) and (0.86, 4.2). Substitute:

[tex]m=\dfrac{4.2-5.6}{0.86-(-40.86)}=\dfrac{-1.4}{0.86+40.86}=-\dfrac{1.4}{41.72}=-\dfrac{140}{4172}\\\\=-\dfrac{140:4}{4172:4}=-\dfrac{35}{1043}=-\dfrac{35:7}{1043:7}=-\dfrac{5}{149}[/tex]

Answer: The slope = - 5/149
