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.

Equation of a line requires either:
a. two points
b. one point, and a slope
What exactly are you trying to do?

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

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
yy=m(xx)
y5=m(xx)
y5=3/8(x)
=3/8x8
