Question

please help

Answer 1

a.) y = - 2x - 2
b.)y = - 3x - 2
c.)y = - 2x - 4
d.)y = - 3x - 4

Answer 2

looks like a slope of -3 and y intercept of -4

Answer 3

i am not able to see the points clearly............can u just repost it by zooming

Answer 4

yes hang on.

Answer 5

well come to think of it..i cant see the points either

Answer 6

thanks @binarymimic, i cant even see the points on the original picture on my screen

Answer 7

Look at the graph to find points where you can see the exact values. (-2,2) and (-1,-1) are two such points. Difference of 1 in the x values gives a difference of -3 in the y values, so the slope is -3 (y goes down as x goes up). The y intercept is just the value of y where the line crosses the y axis, and that is -4. the formula for the line in slope intercept form is y = mx + b where m is slope and b is y-intercept, so y = -3x -4, choice d).

Answer 8

ya...........for sure its d
firstly the y -intercept is -4
and secondly the graph passes through (-2,2)

Answer 9

can you confirm my answer on my next one?

Answer 10

What is the slope of a line perpendicular to the line in this graph?



i got -1/3

Answer 11

i think you forgot to take the reciprocal of it

Answer 12

ohh so it would just be 1/3 instead of -1/3?

Answer 13

Slope of a perpendicular line will be -1/m. m in this graph is 1/3 (3 units to the right for x to make 1 unit up for y), so the correct answer would be -1/(1/3) or -3.
you want the line to be going steeply down from left to right

Answer 14

move 1 unit right in x, down 3 in y

Answer 15

the reciprocal of a # is what you get when you take 1 divided by the #

Answer 16

ohhh so -3..i see. sorry! lol

Answer 17

yeah

Answer 18

always good to mark off a pair of points with the new equation to make sure the line is what you expect!

Answer 19

so easy to make arithmetic or sign errors...

Answer 20

ok i have one more question about graphing..do you guys want me to post in as a new question or just post it here? aand thankyou so much! and yes, I tend to make sign errors a lot lol

Answer 21

i think i have the answer to my question..just want to get a second thought on it

Answer 22

fire away

Answer 23

Given the point (-4, 2) and a slope of -1

Answer 24

thats the answer im thinking...

Answer 25

did you draw that?

Answer 26

heres the other ones that i had to choose from

Answer 27

noo. too bad i still cant see the points..idk why they would put it soo small

Answer 28

If the slope is -1, then it should move one point down and one to the right, like in aaa.gif

Answer 29

look carefully at the choices. which one has (-4, 2) as a point, and a slope of -1

Answer 30

is it safe to choose ccc.gif or no?

Answer 31

They've all got (-4,2) as a point. only aaa.gif has a slope of -1

Answer 32

@whpalmer4 that makes more sense

Answer 33

ccc.gif has a slope of -3/2

Answer 34

idk whati was thinking lol. sorry :P

Answer 35

it's late, unless you're in Asia :-)

Answer 36

haha. can you help me with one more? thats is all. ill open it in a new question thoughif you are willing to

Answer 37

okay
