Question

i need to find the slope of a line-parallel- to each given line.

y=-x+5

Answer 1

the lines is in the form
y = mx + c
where m = -1 in this equation
which is nothing but the slope.
And any line parallel to this line would have the same slope.

Answer 2

Well, a parallel will have the same slope, so the slope will be -1. So, if you graph this line you know a point will be (0, 5) and (1, 4). By the pictures I attached, we can easily see two points which could be a parallel line. So, we do this using the point (1, 2)

y-y1=-1(x-x1)
y-2=-1(x-1)

Now, put this in standard form, y=mx+b:
y-2=-1x+2
+2 +2

y=-1x+4

The slope of this line will also be -1, just like the slope of line y=-x+5.

Hope this helps. :o)

oohh.. now i get it. Thank you.
