Question

Find the slope of line x+4y=16

Answer 1

X+4y=16
4y= x+16
4y/4 = x+16/ 4
y= 4x + 4

Answer 2

-1/4

Explanation:

formula: y=mx+b

x+4y=16

x-4y+4y= 16-4y

x=16-4y

x-16=16-16-4y

x-16= -4y

(x-16)/-1=-4y/-1

-x+16=4y

(-x+16)/4=4y/4

-1/4x+4=y

this makes -1/4 your slope :) hope I explained well
