Question

Use the T-table below to determine 3 solutions to this equation: 4x - 2y = 8

all the X's are

0
1
-2

Answer 1

I have absolutely no idea how to do T-Tables D:

Answer 2

given eqn is 4x -2y = 8
put x = 0 in it and u get
4(0) - 2y =8
-2y = 8
y = 8/-2
y = -4
so first solution is (0, -4)

Answer 3

given eqn is 4x -2y = 8
put x = 1 in it and u get
4(1) - 2y =8
4 -2y = 8
-2y = 8 -4
-2y = 4
y = 4/-2
y = -2
so second solution is (1, -2)

Answer 4

similarly
given eqn is 4x -2y = 8
put x = -2 in it and u get
4(-2) - 2y =8
-8 -2y = 8
-2y = 8 + 8
-2y = 16
y = 16/-2
y = -8
so third solution is (-2, -8)
