Question

y = -x + 5

Answer 1

need help graphing it?

Answer 2

Yes please! I'm not sure if it's just a straight line across the graph or something, with this negative in here.

Answer 3

negative means negative slope.

Answer 4

Also, when I mean straight across, I mean just a straight x or y line. Whoopsie.
I don't know what to do with a negative x by itself.

Answer 5

It's in the form that we like to see :)
y=mx+b

b is where the line lands on the y-axis.
m is the slope of the function.

our b in this case is 5, so we can write that as an ordered pair (0,5).

to graph, plug a value in for x, and then solve for y. write the value down as an ordered pair.

example:
y=-x+5
y=-1+5 --> y=4 --> (1,4)

Answer 6

The negative on the x is letting you know that the line has a negative slope.
Meaning: as you move to the RIGHT, the line should be moving downward.

After you get some points plotted, and draw a line through those points, you should check to make sure that it's moving DOWARD to the RIGHT. :)

Answer 7

Thank you! I feel silly for getting stuck on this, I've done it before, but yeah.
