The equation x + 2y = 16 is in standard form.

What is the slope of the line?

-2

-0.5

0.5

-1

answer b. (The slope of the line is - 0.5)

Step-by-step explanation:

The standard form is y = ax + b

x + 2y = 16

2y = 16 - x

2y = - x + 16

divide all of left and right of the = sign by 2

(2y) / 2 = (-x + 16) / 2

(2/2) * y = - 1/2 * x + 16 / 2

1 * y = - 0.5 * x + 8

y = - 0.5x + 8

So the slope of the line is - 0.5
