Question 207609: I need help graphing two problem which are: 3x-1=5x-y and y=/x/+3
Sorry so you won't get confused the second problem with the x is between two straight lines. That's as close as I can get to showing you it's between two lines. Thank you

You can put this solution on YOUR website!
your first equation is:
3x-1 = 5x-y
you need to solve for y in order to graph this equation.
if you add y to both sides of this equation, then the y moves from the right side to the left side.
if you subtract (3x-1) from the left side of the equation, then (3x-1) moves to the right side.
you get:
y = 5x - (3x-1) which becomes:
y = 5x - 3x + 1 which becomes:
y = 2x + 1
now you can graph the equation by plotting x and y points.
the graph will look like this:

-----
your second problem looks like you mean absolute value of which would make the x between 2 vertical lines.
the equation would look like this:
y = |x| + 3
-----
those vertical lines are found on your keyboard usually on the right side right above the enter key on the same key with the \ but you hold the shift key down and then hit the key, otherwise known as SHIFT \ which gets you |.
-----
you do not have to convert this equation, but you need to plot x and y values and then graph.
the graph will look like this:
graph%28600%2C300%2C-5%2C5%2C-1%2C5%2Cabs%28x%29%29
-----
the other way to write |x| is to call it abs(x) which is consistent with algebra.com terminology that most tutors know.
-----
some other tidbits in case you don't know.
algebra.com terminogy.
x^2 is the same as x squared.
x^n is the same as x to the nth power
sqrt(x) is the same as the square root of x
root(n,x) is the same as the nth root of x
-----
* means multiply
/ means divide
use parentheses to show order of computations.
5+3*2 is the same as 5 + (3*2) = 5 + 6 = 11
(5+3)*2 is the same as 8*2 = 16
operations within parentheses are done first, working from the inner set of parentheses to the outer set of parentheses.
