Use the equation y + 4 = 3x to fill in the missing values in the table below.
x y
-7
8
0
-34
To fill in the missing values in the table, plug the given values of x into the equation and solve for y.
For x = -7:
y + 4 = 3*(-7)
y + 4 = -21
Subtract 4 from both sides:
y = -21 - 4
y = -25
For x = 8:
y + 4 = 3*8
y + 4 = 24
Subtract 4 from both sides:
y = 24 - 4
y = 20
For x = 0:
y + 4 = 3*0
y + 4 = 0
Subtract 4 from both sides:
y = 0 - 4
y = -4
Therefore, the filled-in table is:
x y
-7 -25
8 20
0 -4
-34 -106
