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)
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 |
