How can I write an equation of the linefor example (2,-7) 8x +3y=2. I keep mnissing the most important step. Some of these I have done quite well, like x+6y=9. Please help with the detail because I do remember when to divide.

Answer 1

Equation of a line requires either:
a. two points
b. one point, and a slope

What exactly are you trying to do?

Answer 2

I am trying to wite the equation in the form
y=mx+b

Answer 3

The equation has two given point (3,-8), then an equation Example (3,-8) 8x +3y=6(just an example)

For example (8,5) 8x+3y=7
y-y=m(x-x)
y-5=m(x-x)
y-5=3/8(x-)
=3/8x-8
