Question 53302: I'm a homeschooling mom trying to help my daughter, but this problem we just can't understand. We need to solve(find the system of equations) first by graphing and then by adding or subtracting.
The problem is:
6X-4y=28
4X+9y=-6
We first decided to make X the same so we ended up with
24X-16y=112
24x+54Y=-36
Then we isolated the 24x so we ended up with
24x=112=16y
24x=-36-54y
I think then we have to take 24 by division off from the x side,but I just can't seem to make any sense out of it.
Thanks for your help.

Question 54186: What is the equation for the line represented by this graph? (I don't know how to put a graph on here to show, so I will describe it. It is a straight line with arrows at each end going up from left to right, it passes through 2 on the x-axis and -1 on the y-axis)
My thought was that I would count so you go over 2 to the left, which would give me -2x and down 1 so that is -1. My answer would be y= -2x -1, but I am not sure I am doing it right. Can anyone help without seeing the graph?
