Question

Find the slope of the line that passes through the pair of points.

​(-40.86​,5.6​) and ​(0.86​,4.2​)
simplify

Answer 1

The formula of a slope:

`m=(y_2-y_1)/(x_2-x_1)`

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

`m=(4.2-5.6)/(0.86-(-40.86))=(-1.4)/(0.86+40.86)=-(1.4)/(41.72)=-(140)/(4172)\\\\=-(140:4)/(4172:4)=-(35)/(1043)=-(35:7)/(1043:7)=-(5)/(149)`

Answer: The slope = - 5/149

Answer 2

-.033557047

Explanation:

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

= (4.2 - 5.6)/(.86- 40.86)

= -1.4/ (.86 + 40.86)

= -1.4/41.72

-.033557047
