Question

Find the equation of the line in slope-intercept form (y= mx+b)

M=3/2 and passes through (-6,2)

Answer 1

Have you considered substituting the known values and solving for whatever is left?

Answer 2

No i actially dont know this its confusing

Answer 3

Do you know how to use the slope intercept form?

Answer 4

Yes but not for this

Answer 5

Okay, I can help you. Just give me a minute.

Answer 6

Thanks❤️ Math is not my bestfriend

Answer 7

Y=3/2x+2

I believe that's how you put it into the equation.

Answer 8

Ugh i gotta show my work on how i got it

Answer 9

You have your numbers already.

M=3/2
(-6,2)

Answer 10

Seriously, just substitute.

Here's your equation.
y = mx+b

You have m = 3/2 -- Substitute
This gives
y = (3/2)x + b

You have (-6,2) ==> x = -6 and y = 2 -- substitute
2 = (3/2)(-6) + b

Can you solve for b?

Answer 11

\[(3/2)*(-6)=?\]

Answer 12

You must DO some work in order to show it. Let's see what you can do.

Answer 13

I was just writing that out to make it a little easier for them.

Answer 14

Thanks i can solve for B

Answer 15

Thanksss so much

Answer 16

What did you get after multiplying?

Answer 17

Im doing it now

Answer 18

Alright. Let me know.

Answer 19

You should have gotten -9.

Answer 20

Imma show you how my teacherr did it and YESS YAAY i got that answer

Answer 21

2 = (3/2)(-6) + b

b = -9

2 = (3/2)(-6)+-9

Answer 22

After doing that you should get -18.

2=-18

Divide each side by 2.

2/2=1

-18/2=-9

Answer 23

Well, if your teacher gave you

y = mx+b

and then gave you

M = 3/2

We have a problem. Changing from upper case to lower case in the middle of a problem just is not good form.

Answer 24

Heres some examples my teacher did .... Its confusing

Answer 26

These are all very similar. You just have to recognize the information you are given.

In the first, you are just given the slope. m = something

In the second, you are just given the slope. It's in disguise. Parallel mean SAME slope. Find the slope of the given line and use that for m.

In the third, you are just given the slope. It's in disguise. Perpendicular mean the slope of this line, multiplied by the slope of the desired line, give -1. Find the slope of the given line and calculate the slope that you need. Examples.

If the slope of the perpendicular line is 2, then the slope of your line is -1/2, since 2 * (-1/2) = -1

If the slope of the perpendicular line is 1/3, then the slope of your line is -3, since (1/3) * (-3) = -1

Post the next one (parallel slopes) on a new thread and show your best work.
