Answer 2

hoo boy

anyway let's start with y = 2x + 13

the y-intercept of 13 means there's a point at (0,13)

then the slope of 2 tells us we go up 2 units and right 1 (remember rise/run) to get the next point

after that just connect the two points with a straight line

Answer 3

Okay confused a bit lmao

Answer 4

do you know how to find (0,13) on a graph?

Answer 5

Yes let me show u one sec

Answer 6

Answer 7

good try but remember the x-coordinate comes first

so (0,13) would be on the y-axis

Answer 8

Answer 9

what do we do now?

Answer 10

so then from that red dot, go up 2 units and to the right 1 unit, then draw the next point

Answer 11

Answer 12

good then you should use whatever straight line tool yo uhave to draw a line connecting those two points and extending forever in both directions

Answer 14

awesome

then we repeat the process w/ the other three graphs

B) 2x - y = 17

we can re-arrange this into

y = 2x - 17

so same process as before, you would plot (0,-17), go up 2 units and to the right 1 unit, draw the next point, then connect

Answer 15

okay one sec

Answer 17

should I name them a b c and d?

Answer 18

that would be a good idea

Answer 19

anyway while you're doing that I'll walk you through line C

C ) y = -(1/2)x + 13

the y-intercept is (0,13)

for slope -1/2 you will go over to the right 2 unit and down 1 units (rise/run), draw the 2nd point and connect

Answer 20

from what point?

Answer 21

(0,13)

Answer 22

got it one moment

Answer 23

there is a point there already so I connect from there right?

Answer 24

yes, from (0,13)

Answer 26

good now one more

x + 2y = -14

there's a trick with this question, if you plug in x = 0 you get y = -7 and if you plug in y = 0 you get x = -14

so (0,-7) and (-14,0) should both be on line D so you can just connect these

Answer 28

oof finally

Answer 29

almost, you put line D on (-16,0) instead of (-14,0)

Answer 31

so thats it for this question?

Answer 32

yeah

if they want you to say what shape it is, i think it's supposed to be a parallelogram?

Answer 33

Yes I thought the same

Answer 34

no idea what that has to do w/ superheroes

Answer 35

me neither lol

Answer 37

hoo boy

anyway

item A is the intersection between lines A, and D, take a look at your graph to see what that is

Answer 38

What do you mean?

Answer 39

like, the point where lines A and D cross

Answer 40

oh well I think your graph is a little off whoops :S

Answer 41

LOL what should I change?

Answer 42

well the slopes/intercepts are correct it's just they're a little bit inaccurate in terms of how they're graphed (like they're a bit off-center)

like, we could add more points on A like (-1,11) and (-2,9), etc. and re-do the line to connect all the points

Answer 43

so yeah it's just a little off

Answer 44

so if we look at the new interesection point it's at (-8,-3)

Answer 45

any way answer B is much easier, if you look at lines C and A they intersect at (0,13)

Answer 46

for answer C we are looking at lines B and D (your graph is a little bit off again but I can fix it)

Answer 47

Okayy

Answer 48

so if you look at where B and D intersect it's (4,-9) for blank C

Answer 49

anyway for blank D it's the intersection between line C and B which is hard to see but it should be about (12,7) for blank D

Answer 50

it's kinda hard to get the graphs perfectly right but the key would be to add more points on each line so the function is a bit more accurately graphed

Answer 52

what a weird question

anyway it's shaped like a rectangle, other than that I have no idea what it's supposed to be

Answer 53

what does it mean by saying "Think about this! What item(s) would you place in a cache and where might you hide it? Write
1-2 sentences in the space below to describe your geocaching idea. "

Answer 54

it's just asking for your opinion, so basically what would you hide in a secret place and where would you put it

personally I'd make a time capsule or something and bury it in my backyard, you can use this example or come up with something different

Answer 55

okay got it
if you have a little time to help me with a quiz thats 9 questions that would be great. if not its fine. that would be the end of it tho LOL

Answer 56

is it like a timed graded quiz? I don't think I can according to the QC rules

Answer 57

Nope its not timed

Answer 58

I think it (should?) be ok as long as the assignment allows collaboration

Answer 59

Yes okay I will make a new post tho
