Please Help ! Ill fan you :)

What is the point-slope form of the equation of a line that passes through the point (6, -8 ) and has a slope of -2 ?

A. y + 8 = 2(x - 6 )

B. y + 8 = -2(x - 6 )

C. y - 6 = -2(x - 8 )

D. y - 8 = -2(x + 6 )

Answer 1

Point slope form looks like this:
\[y - y_{1} = m ( x - x_{1})\]

You know your y1 is -8 and your x1 is 6. You know your slope is m = 2. Let's plug it in:

Left hand side:
\[y - y_{1} = y - (-8) = y + 8\]

Right hand side:
\[m(x - x_{1}) = -2(x - 6)\]

Equating both sides gives:
\[y+8=-2(x-6)\]

Which should be the correct answer then?
