Question

What is the point-slope form if the coordinates are (-1,1) and (1,-1)

Answer 1

The point-slope form if the coordinates are (-1,1) and (1,-1)

$\frac{ - 1 - 1}{1 - ( - 1)} = \frac{ - 2}{1 + 1} = \frac{ - 2}{2} = - 1$

y = ax + b = ( - 1 )x + b = - x + b < i guess>

Ok done. Thank to me :>
