Question

The slope-intercept equation of a line is y = -7x - 2. What are the slope and y-intercept of the line?
A.The slope is -7 and the y-intercept is (0, -2).
B.The slope is -7 and the y-intercept is (0, 2).
C.The slope is -2 and the y-intercept is (0, 7).
D.The slope is -2 and the y-intercept is (0, -7).

Answer 1

c

Answer 2

thx

Answer 3

hmm? we have the equation in the form of y=mx+b where m is the slope and b is the y-intercept

Answer 4

so if we're given y =-7x-2
and it's the slope intercept form of y=mx+b. What is m and what is b?

Answer 5

I will explain to you why it's NOT C
If option C were to hold true, we would've gotten the equation y = -2x+7
The original equation, y =-7x-2 contains 2 negative numbers which is -7 and -2
Option C contains 1 positive number and 1 negative number which is -2 and 7

Answer 6

wait wht

Answer 7

try this again.

if we're given y =-7x-2
and it's the slope intercept form of y=mx+b. What is m and what is b?

Answer 8

m is -7 and b is 2

Answer 9

right?

Answer 10

the m is correct.. the b isn't because it's a negative number

Answer 11

so -2

Answer 12

yes so m = -7 and b =-2
It makes sense because we were given y =-7x-2

Answer 13

m = slope and b = y-intercept
therefore
slope = -7 and y-intercept = -2

Answer 14

so a

Answer 15

"A.The slope is -7 and the y-intercept is (0, -2)." correct

Answer 16

thx can you help with one more

Be careful for those direct answer guys.. they are just doing it to gain medals and have no idea what they are doing. That previous user was lucky that it was the wrong answer. Had it been right, that user would've violated the Code of Conduct which is to never give direct answers and to guide users through the learning process.

yeah sure.

Answer 18

If two lines are parallel and one has a slope of 8, what is the slope of the other line?

Answer 19

would it be the same

Answer 20

A.8
B.-1/8
C.-8
D.1/8

Answer 21

parallel lines look like this they don't intersect .

Answer 22

ik so the slope would be 8

Answer 23

the slope is positive though. we are given that there are two parallel lines, but one of them has the slope of 8

Answer 24

its either a or d

Answer 25

wait its -8 :P

Answer 26

really? can you tell me why it's -8? I'm curious ^^

Answer 27

the problem is ... we are not given perpendicular lines.. we have 2 parallel lines

Answer 28

so its not -8

Answer 29

for perpendicular lines we can flip the slope over. perpendicular slopes have opposite signs.

Answer 30

soo for parallel the slope is the same

Answer 31

parallel means that the slopes are the same
parallel lines are just lines that don't intersect.
If I had 2 perpendicular lines I will be intersecting at some point

Answer 32

so its a

Answer 33

??

Answer 34

sorry I was responding to another question . yes it will be the same . since the slope is 8 we have 8 :D

Answer 35

thx
