Q #...10 somebody help me

Answer 1

It is -1, at least thats what i got i hope this helped

Answer 2

The slope of a line can be found, given two points, as follows:

`P_(1)(-5.5,6.1) \\ \\ P_(2)(-2.5,3.1) \\ \\ m=(y_(2)-y_(1))/(x_(2)-x_(1)) \\ \\ m=(3.1-6.1)/(-2.5-(-5.5))=-1`

So this slope tells us the direction of a line and represents the vertical change divided by the horizontal change.
