Question

can somebody help me plot these constraints

Answer 1

\[x+y \le12\]

Answer 2

do you know how to graph the line y=-x+12?

Answer 3

nope

Answer 4

do you know how to find y when x=-1?
or do you know how to find y when x=1?

Answer 5

no

Answer 6

what is y when x=-1?
replace x with -1 and find out like so:
y=-(-1)+12
evaluate/simplify


what is y when x=1?
replace x with 1 and find out like so:
y=-(1)+12
evaluate/simplify

Answer 7

If you aren't sure what I'm asking, I'm asking you to do the following:
Evaluate -(-1)+12
and
Evaluate -1+12

Answer 8

11

Answer 9

-1+12=11

but -(-1)+12=1+12=13


so when x=-1 you have y=-(-1)+12=13

and

so when x=1 you have y=-(1)+12=-1+12=11

So you can graph the ordered pairs (-1,13) and (1,11) as a start to plotting the line.
Then once we have the line we have to work with the inequality part.

Answer 10

plotted the points
not just connect the dots and extend your line passed the dots
