What is the slope of the line with an equation of 5x + 8y = 16?<br> -8/5<br> -5/8<br> 5/8<br> 8/5
zzz [600]

Answer:

Slope m = -5/8

Step-by-step explanation:

5x + 8y = 16

Making y as subject of formula

8y = -5x + 16

Dividing each term by 8

8y/8 = -5x/8 + 16/8

y = -5x/8 + 2

Comparing with y = mx + c

Where m = slope and c the y intercept

Slope m = -5/8
