Find the points that lie on the graph of the equation

Which points lie on the graph of the equation -3x + 6y + 5  = -7 ?
A.)  (-3,6)
B.)  (-2,0)
C.)  (0,-2)
D.)  (6,-3)
E.)  (8,2)

---

If the point lies on the graph, the x,y values, when substituted back in, will create a true statement.

A.) (-3,6)
-3(3) + 6(6) + 5 = -7
-9 + 36 + 5 = -7
-22 = -7
False
not on the graph

D.)  (6,-3)
-3(6) + 6(-3) + 5 = -7
-18 - 18 + 5 = -7
-31 = -7
False
not on the graph

B.) (-2,0)
-3(-2) + 6(0) + 5 = -7
6 + 0 + 5 = -7
False
not on the graph

E.)  (8,2)
-3(8) + 6(2) + 5 = -7
-24 + 12 + 5 = -7
-7 = -7
True 
​on the graph

C.)  (0,-2)
-3(0) + 6(-2) + 5 = -7
0 - 12 + 5 = -7
-7 = -7
True
​on the graph

C.)  (0,-2) and E.)  (8,2) lie on the graph
