The slope for the equation in this problem is 1/212 and the y-intercept is -22

Explanation:

To solve this problem first put the equation into standard form by solving for yy:

4x - 8y + 8y - 16 = 16 - 16 + 8y4x8y+8y16=1616+8y

4x - 0 - 16 = 0 + 8y4x016=0+8y

4x - 16 = 8y4x16=8y

(4x - 16)/8 = (8y)/84x168=8y8

(4x)/8 - 16/8 = (cancel(8)y)/cancel(8)

1/2x - 2 = y or y = 1/2x - 2

The standard form is also:

color(red)(y = mx - y_1) where m is the slope and y_1 is the y-intercept.

Therefore the slope for the equation in this problem is 1/2 and the y-intercept is -2
