Use the equation y+4=3x
to fill in the missing values in the table below. (Type in the numbers for your answers, do not spell the number out, or it will count it wrong.)
x y
-7
8
0
-34
To fill in the missing values in the table, we need to substitute the given values of x into the equation and solve for y.
For x = -7,
y + 4 = 3(-7)
y + 4 = -21
y = -25
For x = 8,
y + 4 = 3(8)
y + 4 = 24
y = 20
For x = 0,
y + 4 = 3(0)
y + 4 = 0
y = -4
For x = -34,
y + 4 = 3(-34)
y + 4 = -102
y = -106
The completed table is:
x y
-7 -25
8 20
0 -4
-34 -106
