Question

When writing linear equations, how do you determine which form of a line to use?

Answer 1

Depending on the information your given.

If given two points, use Point-Slope form.
If given an equation comparing x and x, use Slope-Intercept form
If Given a point and an intercept, use Point-Slope form.

Answer 2

what is the problem you are having to solve
so i can help
or is this the question needing answered

Answer 3

If given an equation comparing x and y (sorry), use Slope-Intercept form

Answer 4

The question was When writing linear equations, how do you determine which form of a line to use?

Answer 5

I'm good at linear algebra I've realized haha

Answer 6

lol kcool but im not

Answer 7

I can teach you if you like all the basics, more advanced, and advanced aspects of linear algebra if you like. Right here! Although a 3 day a week, multiple example/problem solving, quiz, and testing form will be required and is the only way I teach and could take up to 3 weeks.

Answer 8

oh thought it was a problem you did not understand
i am sorry

Answer 9

Lol

Answer 10

no all i want to know is: When writing linear equations, how do you determine which form of a line to use?

Answer 11

i am not good with explaining unless it is by giving and working out the problem step by step so you understand

Answer 12

yess ok

Answer 13

i am gonna leave i am not to good with that

Answer 14

sorry

Answer 15

ok

Answer 16

its ok

Answer 17

@Cosmichaotic how do you determine which form of a line to use? when you do lineaar equations

Answer 18

Like I said, it totally depends on what information you are given.

Like, lets say they give you an equation: 2x + 3y = 4
And that's all they give you.

We want to rearrange this into Slope-Intercept Form: (y=mx+b)
Which using algebra rules we get eventually too...

y = -2/3x + 4/3 where we can say m = -2/3 and b = 4/3
m is your slope
b is your y intercept
That's why they call it slope-intercept form!

After we plot the y-int at (0, 4/3) we can use rise/run with our slope to go down 2 and over to the right 3 units over and over to get our line.

Answer 19

But let's say they give you 2 points.

(0, 0) and (1, 1) and say graph the linear line that passes through these two points.
You could use (0, 0) as (x, y) and (1, 1) as (x1, y1) and use point-slope form:
y-y2 = m(x-x2) to determine the slope and then graph!

Answer 20

Point-Slope Form, Slope-Incercept Form, and the Standard Form Ax + By + C = 0 can all be used.

Answer 21

I hope this helps some.

Answer 22

wait hold on k

Answer 23

You should put: The form used to graph a linear line will depend on the type of information presented to determine the proper/most convenient method. Lol

Answer 24

or should i put this : Linear equations are generally written in the standard form of the line Ax + By = C where A, B and C are real numbers and both of A and B are not equal to 0.

To solve a set of linear equations it may be required to convert one of the equations to a form x = (C - By)/A or y = (C - Ax)/B which is then substituted for either x or y in the other equation.

Also, it is quite easy to convert one form of the line to another with a minimal amount of calculation. A system of linear equations can be solved irrespective of which form of the line the equations are originally in.

Answer 26

That... is like... a freaking AMAZING answer @Queen_Bee1

Answer 27

You just blew me away.

Answer 28

Did you copy that from somewhere??

Answer 29

aww thanx very much, nd lol yea i did copy and paste XD

Answer 30

In the first part mention that C is a constant and can be any real number, including 0

Where {C|C = All real #'s} or something since you did so good explaining everything else haha. Way better than I could.
