Question

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

What is the slope of the line?
-2
-0.5
0.5
-1

Answer 1

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

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
