Hey there!!

Distance formula :

\sqrt{(y2-y1)^{2} + (x2-x1)^{2}  }

Coordinates given :

( 0,1 ) and ( 2,-3 )

( y2 = -3 ; y1 = 1 ) ( x2 = 2 ; x1 = 0 )

Plugging in the values :

... \sqrt{(-3-1)^{2}+(2-0)^{2} }

... \sqrt{(-4)^{2}+(2)^{2} }

... \sqrt{16+4}

... \sqrt{20}

... \sqrt{5}×\sqrt{4}

... 2\sqrt{5} units is the distance.

Hope my answer helps!!

We know the yint, so lets find the slope. (0,-12) and (8,-2) -2--12/8-0 or 10/8 or 1.25
So, the slope is 1.25
The answer is y=1.25x-12
