Answer 1

can some help me understand these?

Answer 2

maybe post a ss.

Answer 3

?

Answer 4

post a screen shot of the question

Answer 6

ok i got you.

Answer 7

Press Shift + Ctrl + that button at the top of the screen that had a square with 2 lines next to it

Answer 8

Hi there! I can help you!!

The equation for slope-intercept is

`y=mx+b`
where `m = slope` and `y = y-intercept`

Lets start with question 1, `y = 12x + 7`

what do u think the slope is?

Answer 9

ok back

Answer 10

oh and 12

Answer 11

Thats correct!

Now for question 2, `y = −7x − 2`

whats the y-intercept?

remember to pay attention to the signs!!

Answer 12

-7

Answer 13

?

Answer 14

no that wouldn't be correct

y=mx+b

where m = slope and b = y-intercept

sorry, I wrote this but there was a typo

the equation: y = −7x − 2

m = -7
b = ?

Answer 15

oh -2

Answer 16

Yep, that would be correct.

Sorry about the typo, I didn't mean to confuse u :/

Answer 17

it ok

Answer 18

thx for the help
