Answer:
(x, y) = ( 5, 6)
(x, y) = ( - 1, 0)
Step-by-step explanation:
Plug
in the equation
we find:
(x, y) = ( 5, 6)
(x, y) = ( - 1, 0)
Answer:
4 y = -4 x + 8 or y = -x + 2
y - x = -2 or y = x - 2
using the standard form for a line y = m x + b
We see that in one equation m = -1 and in the other m' = +1
this is the condition for perpendicular lines
