=(x-8i)(x+8i)
x^2+8ix-8ix-64i^2
x^2-64i^2
x^2-64(-1)
x^2+64
2.)
=(4x-7i)(4x+7i)

16x^2-49i^2
16x^2-49(-1)

Hope this helps :)
95 is 20% of 475
to check answer do 475 times .2
You could use the equation y=mx+b
Find the slope of the two coordinates. I would personally suggest using stack and subtract:
(0,2) 2-5 -3 3
(2,5) -------= ------= -----
0-2 -2 2
We have the slope but we need to find the y-intercept.
y=3
--x+b
2
Plug one of the coordinates in the constructed equation above:
2=3
-- (0)+b
2
2=0+b
-0=-0
------------
b=2
We found the slope and y-intercept. Now we have our complete equation. The equation is:
y=3
--x+2
2
Have a blessed day!
