Answer:
7
Step-by-step explanation:
One solution was found :<span> x = 4</span>
1 2
------- = --------
4a 3
cross multiply
2(4a) = 1 * 3
8a = 3
a = 3/8 or a = 3 over 8
answer
<span>3 over 8</span>
You find the slope by putting the points in the formula y2-y1/x2-x1
when you plug them in it should look like this
-4 -1/8-8
then you would add or subtract, when you do you would get
-5/0
this can't be divide so the slope of this 2 points is undefined
Hope this helped
