Find the number in the tenth place
8
8
and look one place to the right for the rounding digit
7
7
. Round up if this number is greater than or equal to
5
5
and round down if it is less than
5
5
.

PSF: y - y₁ = m(x - x₁)
Standard Form: ax + by = c

1). y - 3 = -4(x + 8) 2). y = -4x - 29
y - 3 = -4x - 32 + 4x + 4x
+ 3 + 3 ---------------------------------
----------------------------- 4x + y = -29
y = =4x - 29
This is what I got hope it helps!
3y-9=6
add 9 to both sides
3y=15
Divdide both sides by 3
y=5 is the answer
The function is equal to (x+2) / (x+2)(x-2), so when you simplify, it would be 1/(x-2). This means that there is a hole in the graph at x=-2, and a vertical asymptote at x=2.
