Find the slope of the line that passes through the pair of points. <br><br> (1.8, –3.4), (6.8, –8.4)
elixir [45]

Answer:

-1

Step-by-step explanation:

If a straight line passes through the known points (x1, y1) and (x2, y2), the its slope is given by m = \frac{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 = \frac{-3.4-(-8.4)}{1.8-6.8}= -1 ( Answer )
