<span>Hello : let
A(2,-1) B(8,4)
the slope is : (YB - YA)/(XB -XA)
(4+1)/(8-2) = 5/6</span>
<span>an equation for the line in point-slope form is : y-(-1) =( 5/6)(x-2)
y+1 = (5/6)x -5/3
6y+6 = 5x -10
</span><span>the equation in standard form is : 5x-6y = 16</span>
B. It is not true. The point at x=0 is not part of a solution for the piece wise function.
The equation 
has 2 and x in common. This means you can factor both the 2 and x out of the equation like so...
2x(
)
Hope this helped!
