Step-by-step explanation:

8x-7y+6=0

=>7y=8x+6

=>y=(8/7)x+6/7

differentiating both sides w.r.t x,

we get,

Slope=dy/dx=8/7

for finding y intercept,

put x=0,

we get,

8(0)-7y+6=0

=>7y=6

=>y-intercept=y=6/7

Answer: y = -8/7x + 3

Step-by-step explanation: To put this into slope-intercept or y = mx + b form, start by subtracting 8x form both sides to get 7y = -8x + 21.

Now just divide both sides by 7 to get y = -8/7x + 3.
