(5.25, 1.25)
left parenthesis 5.25 comma 1.25 right parenthesis
(−6, −1)
left parenthesis negative 6 comma negative 1 right parenthesis
(4, 1)
left parenthesis 4 comma 1 right parenthesis
(−7.25, −1.25)
(-6, -1)
2x+6y=−18
x=5y−1
=================
2 (5y-1) + 6 y = -18
10 y - 2 + 6 y = -18
16 y = -16
y = -1
then x = 5 (-1) - 1 = -6
so
( -6 , -1 )
