Answer:
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
