Question

Algebra1 (medal)
plz help i dont uderstand part 1
Part 1: When writing linear equations, how do you determine which form of a line to use?

Part 2: Choose 1 set of points from the choices below. Then, solve the problem and post your solution, showing your steps.
Write an equation in point-slope form for the line that passes through one of the following pairs of points (you may choose the pair you want to work with). Then, use the same set of points to write the equation in standard form and again in slope-intercept form.

Point pairs
(5, 1), (–3, 4)
(0, –2), (3, 2)

Answer 1

This sounds like they wrote up a lesson where they explain the different ways to write an equation for a line and how to choose a particular form.

Answer 2

no not really

Answer 3

All the forms are equivalent in that they represent the same line, so in some sense it does not matter which you use.

But slope-intercept might be easier to plot (by hand-- a computer would not care)
or point-slope might be easier to write down if you are given the slope and a point.
or if you have two linear equations (a system), then standard form would be easier to solve (using elimination).

Answer 4

But I don't really know what they told you, and sometimes they ask these type questions to test if you read the lesson.

Answer 5

ok so i can preety much just say that you can use any type of a form to solve a problem. unless the question asks me to use a certain one ?

Answer 6

You could, but I am guessing they told you something else, because some forms are easier to use for some problems (as I tried to explain up above)

Answer 7

ok thx
