Question

I need some help with slope-intercept forms

Answer 1

Here is the question..

Answer 2

Find the slope first :)
\[\LARGE \frac{y_2-y_1}{x_2-x_1}=slope\]
\[\LARGE \frac{-3-1}{3-1}=slope\]

Answer 3

Ok I found that the slope is -2, is that correct? If so what do I do next?? Thank you for helping.

Answer 4

@pooja195

Answer 5

Good -2 is correct
now we ahve y=-2x+b
To find the b value just take one of the given coordinates an plug them into the equation

Answer 6

And I take the x from one of the x coordinated too? Or no @pooja195 ?

Answer 7

-3=-2(1)+b
solve for b

Answer 8

So, 1 would be B. -3=-2(1) + 1 @pooja195

Answer 9

No
-2 times 1 =?

Answer 10

-2 + 1 would be -2. Oops. I am still not getting the correct answer though

Answer 11

@pooja195

Answer 12

-3=-2+b
add 2 to both sides
-3+2=?

Answer 13

So -1 would equal B

Answer 14

Yes

Answer 15

y=-2x+b <--- replace with -1

Answer 16

Our equation doesn't show up on the multiple choice as one of the possible equations..

Answer 17

@pooja195

Answer 18

Can you show me the choices?

Answer 19

@pooja195

Answer 20

Slope is wrong

Answer 21

Oooh. Huh.

Answer 22

\[\LARGE \frac{y_2-y_1}{x_2-x_1}=slope\]
\[\LARGE \frac{1--3}{3-1}=\]

Answer 23

Find the slope

Answer 24

Ok so the slope is positive 2.

Answer 25

Correct
y=2x+b
You can use either (x,y) point you want..the answer will be the same:

(1,-3). y=mx+b or -3=2 × 1+b, or solving for b: b=-3-(2)(1).

Answer 26

Can you solve for b?

Answer 27

B would be 5, correct? Or -5

Answer 28

Yes -5
is correct
y=2x+b<---replace with -5

Answer 29

Ok so the answer would be D. y=2x-5

Answer 30

Yay! I got a 100%, thank you very much for helping me and not just giving me the answer. :D
