Question 126343: All of the examples show how to solve and graph equations with 1 variable with a number before it and one separate variable, for example:
4x-y=3 (equation1)
3x=y=4 (equation2)
I can solve those, but it confuses me when they ask me to graph problems, such as the one I'm having difficulty with.
6x+2y=16 (equation1)
-2x+y=-2 (equation2)
I solved for y in equation2 and got:
y=2x+2
It is easy to solve for y in equation2, but how do you do the same for equation1?

Question 126534: I am asked to solve and plot the x and y intercept. 2y=9
I know this how to solve for y
2y diveded by 2= nine divided by 2
2y/2=9/2
Will give me a solution of y= nine divided by 2
Solution for Y=9/2
I would plott Y on the graph as (0,9/2)
I dont underderstand how do I solve for x when there is no x given in 2y=9?
