Question

Which equation is a point slope form equation for line AB ?

A: Y+6=-2(x-1)

B: Y+2=-2(x-5)

C: Y+1=-2(x-6)

D: Y+5=-2(x-2)

Answer 1

The correct answer is y + 2 = -2(x-5). 

Original Equation: y = -2x + 8

Test Option B:

y + 2 = -2(x-5)

   y + 2 = -2x + 10
       - 2             - 2
-----------------------------
   y = -2x + 8
