Question

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

(1.8, –3.4), (6.8, –8.4)

Answer 1

The answer would be -1

Answer 2

-1

Explanation:

If a straight line passes through the known points (x1, y1) and (x2, y2), the its slope is given by
`m = (y1-y2)/(x1-x2)`

Now, in our case the straight line passes through the points (1.8, - 3.4) and (6.8, - 8.4).

Therefore, the slope of the required straight line will be
`m = (-3.4-(-8.4))/(1.8-6.8)= -1` ( Answer )
