Answer 1

do you know how to put equations into slope intercept form?

Answer 2

sort of

Answer 3

okay well gimme a minute

Answer 4

thank you

Answer 5

This is graphing inequalities I suppose

Answer 6

i think

Answer 7

Okay so the first is already in y- intercept form and that would look like this on a graph because the y-intercept is -2 and the slope is -2 over 1.(up 2 and over -1) since it is an greater than or equal to symbol it should be a solid line shading upwards

Answer 8

do you understand?

Answer 9

yes thank you :)

Answer 10

On the second equation, we have to put it into slope-int form and that is y=mx+b. B is the y-intercept and m is the slope.
\[y+x \ge0\]
\[y+x-x \ge -x+0\]
This would leave y by itself equaling
\[y \ge -x+0\]

Answer 11

So tell me. what would the slope and the y- int be?

Answer 12

so the slope is -1 over 1 and the y intercept is b which is 0

Answer 13

Good! So would it be a solid or dotter line shading which way?

Answer 14

dotted*

Answer 15

they would both be solid lines because they are both inequalities are greater than and equal to.

Answer 16

Good! So plotting both these on a graph would look like this and you can see the intersecting point is at (-2,2)

Answer 17

Great job @domebotnos :)

Answer 18

thank you, you too as well :D
