Answer:
Slope is - 4.
Step-by-step explanation:
The given points are (-1,10), (1,2), (3,-6) and (5,-14).
Now, we have to find the slope of the line containing these points.
We can pick any two points to find the slope. Let they are (-1,10) and (1,2).
Now, we know that the slope of a straight line passing through any two known points and is given by
........... (1)
Therefore, the slope of the straight line through the given points will be
{From equation (1)} (Answer)

<span><u> 2/3 c = -8 </u>
Multiply each side of the equation by 3 : 2 c = -24
Divide each side of the equation by 2 : <em>c = -12</em> .
========================================
Did you mean to say (2) / (3c) = -8 ?
If so, then let's attack it this way:
Multiply each side of the equation by 3c : 2 = (-8) x (3c) = -24c
Divide each side of the equation by 24 : 2/24 = -c
Multiply each side by -1 : <em> c =</em> -2/24 = <em>-1/12</em>
