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

-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.
Substituting x = -7 into the equation y + 4 = 3x:
y + 4 = 3(-7)
y + 4 = -21
y = -21 - 4
y = -25
So when x = -7, y = -25.
Substituting x = 8 into the equation y + 4 = 3x:
y + 4 = 3(8)
y + 4 = 24
y = 24 - 4
y = 20
So when x = 8, y = 20.
Substituting x = 0 into the equation y + 4 = 3x:
y + 4 = 3(0)
y + 4 = 0
y = 0 - 4
y = -4
So when x = 0, y = -4.
Therefore, the filled table is:
x y
-7 -25
8 20
0 -4
