LINEAR EQAUTIONS HELP

Answer 1

go for it

Answer 2

thanks

Answer 3

I need help figuring out which line equation to use given the following information.

I have two points: a. (-1,4),(-5,2)

Should I use point-slope,slope intcerpt, or standard form

Answer 4

Slope intercept is easier to me.

Answer 5

are u sure?

Answer 6

Yes.

Answer 7

i thought it was point slope

Answer 8

@jjuden , any of your thoughts?

Answer 9

whats the best for you

Answer 10

It all gives you the same out come, I just prefer slope intercept.

Answer 11

you do what is easiest for you

Answer 12

it is not easiest form, it has an answer.

Answer 13

like for point slope, you need a point and a slope, for slope intercept you need the slope and y intercept.

Answer 14

Well slope is change in y over change in x.
So you have both slope and a point.

Answer 15

You can solve for either one with that information though. Thats the thing.

Answer 16

true

Answer 17

I think it's asking for point slope though. Maybe.

Answer 18

For me, it depends on if they are asking for the solution in point-slope or not. If they do not specifically ask for the answer in point slope, then I would use slope intercept.

Answer 19

thank you...can i ask 1 more Q?

Answer 20

ask away

Answer 21

Sure.

Answer 22

thank you

Answer 23

If you have an x intercept of 6, and a y intercept of 3, can you figure out the equation with steps and tell me if the given information is suitable for point slope,slope intercept, or standard

Answer 24

can any one understand the Q?

Answer 25

Yes! One sec!

Answer 26

With the intercepts you can find two points. X-intercept= (6,0) and Y-intercept= (0,3). Do you understand that?

Answer 27

Slope is \[\frac{ \Delta y }{ \Delta x }\]
aka change in y over change in x.
Change in y is -3 and change in x is +6. Reduce:
\[-\frac{ 3 }{ 6 } = -\frac{ 1 }{ 2 }\]
Since this problem gives you two points and one of the points is the y-intercept I think it is better to use slope intercept form.
\[y =mx+b\]
m= slope slope = -(1/2)
b= y-intercept= 3
Slope Intercept form is:
\[y=-\frac{ 1 }{ 2 } x + 3\]
