Give the equation of the line perpendicular to Line 1 which passes through 

 

Include the full equation as your answer.

The equation is what ?

Answer 1

y=x+b

y=mx+b where m=slope=1 and b=y intercept. Plug in m=1 and plug in the point y=-10, x=2 to calculate b

-10=2+b

b= -12

y=x-12 is the line parallel through the point (2,-10)
