Answer:
<h2><u><em>
-3x + 9</em></u></h2>
Step-by-step explanation:
(6x + 14) - (9x + 5) =
6x + 14 - 9x - 5 =
<u><em>-3x + 9</em></u>

The equation of given line is ~

Let's use the point slope form of line to find the equation of given line ~
that is ~
I guess just work backwards.
x=-3
2x=-6
x=-x-6
There ya go :P
Answer: -1/2
Step-by-step explanation: to find slope, use the equation (y2-y1) / (x2-x1)
(-6 - -3) / (7 - 1)
-3 / 6
= -1/2
