Question

@butterflydreamer @babynini
A line has a slope of 3 and contains the point (−1, −8).

Which equations represent the line?

Choose all answers that are correct.

A.
−3x + y = −5

B.
3x + y = −5

C.
(y – 8) = 3(x − 1)

D.
(y + 8) = 3(x + 1)
i think it is a and d?

Answer 1

Yes, A and D are correct

Answer 2

@Miracrown doesn't A make it a negative slope?

Answer 3

Oh sorry, nevermind!

Answer 4

Nope, as that is not in the slope-intercept form

Answer 5

thanks guys!

Answer 6

one more @Babynini @micracrown ?

Answer 7

Sure :) I shall try my very best!

Answer 8

ok theres screen shots

Answer 9

@Babynini

Answer 10

theyre out of order

Answer 11

@Babynini

Answer 12

Ok, give me a moment to open all those :P

Answer 13

ok

Answer 14

The first thing to do would be write the equation in it's usual form.

Answer 15

ok so.. that would be..?

Answer 16

idk how to do that

Answer 17

the equation for a graph is: y =(slope)x + (y intercept)
So simplify what you have: (y+1)=3/5(x-3)
to fit that. Does that make sense?

Answer 18

yes

Answer 19

Ok, work that out and then show it to me

Answer 20

(hint: it's helpful to make the "1" on the left have a denominator of 5 like the other fractions. So your new equation would be:
y + 5/5=3/5(x-3)

Answer 21

i dont really get it

Answer 22

Hm, okay. Let's see.
