The slope of the line x + 2y = 16 is -0.5.
According to the given question.
We have a equation
x + 2y = 16
As we know that the slope intercept form of the line is given by y = mx + c
Where, m is the slope of the line.
Since, the given equation x + 2y = 16 can be written as
2y = 16 -x
⇒ y = 8 - x/2
Compare the above equation with the y = mx + c, we get
m = -1/2 = -0.5
Hence, the slope of the line x + 2y = 16 is -0.5.
