Question

Can someone please help me answer this question?
I have an idea of what it could be but I'm not sure...
Question~
graph the following inequalities. The accuracy of the line, if the line is dashed or solid, and which side you shade are important components. Make your points in yellow, the line in blue and shade in red.
x + y > -4
NOTE* The > has a line under it

Answer 1

So would X= -4+ -1y?

Answer 2

@phi could you try to help me please?

Answer 3

move the x to the other side to get y > -x - 4

Now graph that.

Answer 4

**The > has a line under it***
if you can't type in \( \ge\) you can use >=
it means greater than or equal

Answer 5

if you have a >= or <= you will make the line solid
if it is just > or < then use a dashed line

your problem will use a solid line

Answer 6

yes sir/ ma'am, I know that part

Answer 7

to plot the line,
the normal slope intercept form is
y= mx + b

in other words, write your equation
x+y >= -4
by adding -x to both sides and simplifying. you get
y >= -x - 4

now put in x=0. what do you get for y ?

Answer 8

y=-4?

Answer 9

yes, so plot (0, -4)
do you know how?

Answer 10

Hmm I'm a little confused, would you mind showing me the points I should plot? I can draw the line and everything else, but I don't know where the points should be

Answer 11

First, let me fix the 2nd point
I said pick x=1 and figure out y
y= -x-4 so y= -1-4= -5
and the point is (1, -5)

Answer 12

to plot (0,-4)

find the origin (where x and y cross)
now count straight down 4 steps and put a yellow dot there.
can you do that ?

Answer 13

Like that? @phi I know the dot isn't yellow I will fix that in my lesson

Answer 14

yes looks good
now for (1, -5)
go to the origin and count to the right 1 step, then down 5 steps

Answer 15

you should be 1 to the right and 1 below the first point
