Question

Can anyone help with math? I will fan and medal.

Answer 1

Hi
Welcome to openstudy :)
start with the basic info
y=mx+b <---slope-intercept form
m=slope
Can you write the equation with the slope in it?

Answer 2

i got y=-2x+2

Answer 3

I think you flipped the numbers around check again :)

Answer 4

y=2x+-4?

Answer 5

No, you has the right numbers just flipped the slope and y-intercept around remeber that our slope was postive 2

Answer 6

Now take your coordinate nu,bers and plug those into the equation :)
4=(2)(3)+b
now solve for b

Answer 7

im confused

Answer 8

Where are you confused? What step? :)

Answer 9

i think the first step

Answer 10

i might have done it wrong

Answer 11

Ok let me explain this better :P
We are give the slope 2
slope intercept form is
y=mx+b
slope = m
y=2x+b
now we need to find the b in our equation to do this we would plug in the coordinate pair numbers
y=4
x=3
4=(2)(3)+b
solve for b

Answer 12

b=-2

Answer 13

Good so you would plug that into
y=2x+b
plug that in place of b

Answer 14

y=2x+-2

Answer 15

you can get rid of the + sign
y=2x-2

Answer 16

the plus is mandatory in the equation

Answer 18

oh didn't see that...yea just leave it in their :) you have it right :)

Answer 19

okay
