Write Y+2=1/3x in standard form
solong [7]

The standard form of a line is in the form

Ax + By = C

A, B and C are integers, and A is positive. Let's start with multiplying the whole equation by 3 to get rid of denominators:

3y+6=x

Subtract 3y from both sides:

6=x-3y

Which of course is equivalent to

x-3y=6

Which is the standard form, given the coefficients A=1, B=-3, C=6.

What is the vertex of the quadratic function f(x)=(x-8)(x-2)?
7nadin3 [17]
Change the function into vertex form:
f(x)=x²-10x+16
make a square by (adding half of -10)², which is 25, then subtract it:
f(x)=x²-10x+25-25+16
f(x)=(x-5)²-9
so the vertex is at (5,-9)

another way to do it: 
f(x)=x²-10x+16
the vertex is when x=-\frac{b}{2a}, b=-10, a=1 in this case.
x=-(-10/2*1)=5
plug x=5 into the quadratic function, you get f(x)=-9
