Question

the equation of the line :

9x-2y=7 (7,-1)?

Answer 1

9(7)-2(-1)=7

now solve

Answer 2

I did that and I got 61.

Answer 3

yeah. scratch what I said. you first need to find the slope of the equation (set 9x-2y=7 equal to y) and then do some other stuff........look at this link for an example: http://www.algebra.com/algebra/homework/coordinate/Linear-systems.faq.question.226304.html

Answer 4

Im stuck at y-(-9)=(8/9)(x-8)
