Question 205596: The question is: Find an equation of a line parrallel to -3x-3y=5. I have no idea what to do. I thought I might need a graph but it doesn't say to use one. I don't know if i should add anything or subtract. HELP ME PLEASE!

You can put this solution on YOUR website! Find an equation of a line parallel to -3x-3y=5
---
You only need to find the slope as all lines that
are parallel have the same slope.
---
Put the given equation into slope-intercept form:
y = -x - 5/3
The slope is -1
-------
An equation of a line that would be parallel is y = -x + 2

All parallel lines have the same slope.
Find the slope of the given line by putting it into slope-intercept form (that means solve for y).
-3x-3y=5
-3y = 3x+5
y = -x - 5/3
So the slope, m, is -1
Use y-y1 = m*(x-x1) to find a line thru the point (x1,y1)
Use any point.
Thru (0,0):
y = -x That's one line that's parallel.
Thru (2,4):
y-4 = -1*(x-1)
y-4 = -x+1
y = -x + 5 That's another.
----------
Thru any point:
y = -x + any number --> lines parallel to the given line.
Or, x+y = any number

You can put this solution on YOUR website! -3x-3y=5,,,,,remember slope intercept form ,,,y=mx+b
.
-3y=3x+5,,,,,divide thru by (-3)
.
y= (-1)x +(-5/3),,,,,,,,,line of slope(-1),,y intercept of -(5/3)
.
a parallel line has same slope, different y intercept,
.
such as,,,,y= (-1)x +(+5/3)
.
but this in standard form is,,,3y = -3x + 5,,,or,,,-3x -3y = -5
.
to generalize, a set of parallel lines ,,,has same form as original
.
except change constant.
