Answer 3

Do you know how to graph the equation 5x + 7y = 35 ?

Answer 4

wouldn't I make it y=-5/7x+5?

Answer 5

good

Answer 6

so (0,5) down 5 over 7

Answer 7

so what is the second point on this graph?

Answer 8

5x+7y=-35
so y=-5/7x-5
(0,-5)

Answer 9

(0,5) is on y=-5/7x+5

what's another point on y=-5/7x+5 ?

Answer 10

I don't know

Answer 11

you said "down 5 over 7"

what did you mean by that?

Answer 12

(7,0)

Answer 13

good, you start at (0,5) and go down 5 and over to the right 7 to land on (7,0)

Answer 14

so y=-5/7x+5 has the two points (0,5) and (7,0)

Answer 15

yes. That's it? would I have to shade or anything?

Answer 16

plot those two points, draw a line through them and make this line a dashed line

Answer 17

the line is dashed because there is no line under the inequality sign (so we're excluding this boundary)

Answer 18

no do not shade until the boundaries are set up

Answer 19

Ah ok... and shading?

Answer 20

you need both lines drawn

Answer 21

What does that mean?

Answer 22

you need to plot both 5x + 7y = 35 and 5x + 7y = -35

Answer 23

once you've done that, you can shade the correct region

Answer 24

is that correct?

Answer 25

yes it is, hopefully you see how to get that?

Answer 26

I think I do. I may post another just to double check I'm doing it right. Thank you!

Answer 27

you're welcome
