Question

help please

Answer 1

your idea?

Answer 2

my idea was -9/1, for the equation, but was proven wrong

Answer 3

What is the slope point equation of a line?

Answer 4

y=mx+b

Answer 5

yup, how to find m?

Answer 6

with the two points for the equation y-y2/x-x2

Answer 7

yes, so, your m =???

Answer 8

my m is 9/-3

Answer 9

=?

Answer 10

m=-3

Answer 11

yuuuuuuuuuuuup

Answer 12

Now, replace that m back to y = mx +b, you have y = -3x +b, right?

Answer 13

yes

Answer 14

You have 2 points, pick one of them, just one. which one do you want to pick?

Answer 15

-2,7

Answer 16

That means x =-2, y =7, right?

Answer 17

from y = -3x +b
add 3x both sides, what do you get?

Answer 18

3x+y=b

Answer 19

perfect, now replace x =-2, y =7 into it, what do you get for b?

Answer 20

1

Answer 21

YYYes

Answer 22

so far, your m =-3, your b =1
plug all in y =mx +b, what do you get?

Answer 23

so it would be y=3x-2

Answer 24

Come on!! redo

Answer 25

it has to be in slope-intercept form
