Slope = (1-0)/(-2-4) = -1/6
<span>POINT-SLOPE equation
y - 0 = -1/6(x - 4)
hope it helps</span>
Change 3 to 6 and 2 to 4
Now Do
3/6 + 5/6 = ?
? = 8/6
8/6 = 1 2/6
1 2/6 = 1 1/3
16 n^2 -10n + 129 = 8n^2 -8
We collect the terms:
8n^2 -10n + 137 = 0
The steps for completing the square:
1) Move the "non X" (or "non N") term to the right:
8n^2 -10n = -137
<span>2)<span> Divide the equation by the coefficient of N² which in this case is 8
n^2 -1.2n = </span></span><span><span>-17.125
</span>
3) Take the coefficient of "N"; divide it by 2; square it; add it to both sides of the equation.
-1.2 / 2 = -.6
-.6^2 = .36
</span>
n^2 -1.2n +.36 = <span>-17.125
+.36
Take the square root of both sides:</span>
(n-.6)*(n-.6) = sq root(

-16.765

That's about as far as I can go.
Answer:
The graph should look almost exactly like this. I used a virtual graphing chart to assist, since it is capable of showing more than paper alone.
