Answer 1

@Vocaloid

Answer 2

yikes

unfortunately you just have to plug every set of x and y coordinates in, one at a time, to see which answer choice gives two equal sides

Answer 3

where do I plug it in

Answer 4

so like, (-4,1) means x = -4 and y = 1

so y + (1/4) = -4(x+1)

becomes

1 + (1/4) = -4(-4+1)

then you'd just see if these two sides are equal (it's not) so we'd test choice B

Answer 5

got it

Answer 6

what did you get for the previous choice?

Answer 7

im working on it rn

Answer 8

not b either

Answer 9

good, keep going

Answer 10

I think its c

Answer 11

so if you plug y + 1/4 = -4(x+1) you get

y + 1/4 = -4(3+1)

y = -4(4) - 1/4 which is -16 - 1/4 choice D

Answer 12

anyway let's go to q2

-Ax - By = C (plugging in all the signs)

we can add By to both sides to get and subtract C from both sides

By = -Ax + C

so with that being said what might the best choices be?

Answer 13

B?

Answer 14

i know its negative but is it x or y?

Answer 15

wait

Answer 16

oh so its A and C

Answer 17

yeah I botched up the calculations whoops

-Ax - By = C

should end up being

By = -Ax - C

Answer 18

so B and D?

Answer 19

yup

All one question

Answer 21

so since we have the formula

y - y1 = m(x-x1)

and
our problem is

y - 2 = 3(x-1)

the graph crosses (1,2) and has slope 3

any ideas which graph is best?

Answer 22

C

Answer 23

awesome

Answer 25

y = 4x - 2 means slope 4 and intercept -2, right? so which graph might match?

Answer 26

B?
not quite positive

Answer 27

good attempt but a positive slope means we should be going up from left to right

Answer 28

you mean right to left?

Answer 29

because B is left to right

Answer 30

is this choice B?

Answer 31

yes

Answer 32

so this one has a negative slope (it's going down as you go from L to R)

so it can't be this one

Answer 33

so we'd want a graph that goes up

Answer 34

A or C not sure which one tho

Answer 35

remember we want the one that has y-intercept -2

Answer 36

A

Answer 37

perfect

Answer 39

so any ideas? as the grade increases to 12 do the weights tend to go up or down?

Answer 40

The weight increases, A

Answer 41

look carefully, B is the one that says weight increases :P

Answer 42

sorry my bad I meant B

Answer 43

awesome

Answer 44

http://prntscr.com/ktrhd4

Answer 45

D?

Answer 46

good but there's one more

negative slope means one variable goes up, the other goes down

so B+D

Answer 47

http://prntscr.com/ktrhzc

Answer 48

any ideas? if you drew an imaginary line through the points would the slope be + or -?

Answer 49

positive

Answer 50

A

Answer 51

good

Answer 52

http://prntscr.com/ktrifg

Answer 53

well S is the score which is the dependent variable

so the equation should look something like

S = ____H + _____

if you tried drawing an imaginary line through the points do you think the equation would look more like A or B?

Answer 54

A

Answer 55

awesome so A = your solution

Answer 56

last one:
http://prntscr.com/ktrj5u

Answer 57

so you have 5x + 2y = 20

try solving for y

Answer 58

C

Answer 59

or D

Answer 60

yeah D
