Question

y = x2 − 5x − 3
6x − y = −27

y = x2 − 5x + 3
6x − y = 27

y = x2 + 5x + 3
6x + y = −27

y = x2 + 5x − 3
6x + y = 27

Answer 3

i gt d

Answer 4

got*

Answer 5

the line has negative slope, and its y intercept is definitely negative.

I would put each equation of the line into y = mx+b and look for the equation that has a negative m, and a negative b

Answer 6

The first option
6x − y = −27
becomes 6x = y-27 (add y to both sides)
then 6x+27 = y (add 27 to both sides)
or
y= 6x+27

that loses twice: slope is positive and y-intercept is positive. So rule out choice A

Answer 7

Do the same for the other choices.

Answer 8

@phi that would rule out b also

Answer 9

yes choice b has positive slope

Answer 10

i wana say its c

Answer 11

what do you get for the eq in y= mx+b form ?

Answer 12

y=-6x-27

Answer 13

@phi

Answer 14

yes, that has negative slope and negative y intercept.

If you check choice (d) it should not work

Answer 15

i have two more questions, can you help?

Answer 16

if you make them a new post.
