y=-x-3 and y=-x+2
2007-01-12 11:45:09 · update #1
y= -x-3
y= -x+2
they are both equal to y
-x-3= -x+2
-3= -2
-3 can't be equal to -2, so there is no solution.

y=-x-3 and y=-x+2
you want to graph them
since x is negative in both, your line is going to decrease.
also, since the leading coefficient is 1, they decrese by 1 every time y increases by one.
and last the last numbers -3 and 2, is where your line crosses the y axis.
sounds like youre in algebra, it might be time u get a graphing calculator. aww. you sound so young! dont worry. i was kinda confused too when i started algebra in 6th grade! but look at me now! 10th grade and already taking precal! (and have the highest grade in my class):P

y = -x - 3
y = -x + 2
set them equal to each other
-x - 3 = -x + 2
0x = 5
x = 5/0
since "x" is undefined
ANS : No Solution because the 2 equations are parallel

y=-x-3
y=-x+2
You want to add x from both sides:
x+y=-3
x+y=2
That's how a system of equations should look like. By the way, the answer is no solution.
