Question

please answer this:

How will you determine the equation of the line if the given are two points of the line?

i really need the answer...




thank you

Answer 1

first find the slope, m=(y2-y1)/(x2-x1)

Answer 2

then write it in slope intercept form
y-y1=m(x-x1)

Answer 3

What if I make up two points and work the problem I made up? Will that help?

Answer 4

okey....

Answer 5

Points ( 2, -1 ) and ( -4, -5 ) lie on a line. Find the equation of the line that contains then. Leave your answer in y = mx + b form.

Answer 6

First, get the slope. Think of slope as change in y over change in x.

m designates the slope of a line and has formula [y2 - y1] / x2 - x 1 ] . The y2 is not y^2 but what we call y sub 2 because the 2 is a subscript which is hard to type.

Answer 7

One of our points will be (x1, y1) and the other (x2, y2) It does not matter which is which.

Answer 8

Let (x1,y1) be (2, -1) and let (x2, y2) be (-4, -5)

Questions so far?

Answer 9

what is y=mx+b

Answer 10

That is the form we will leave the equation of our line in. So, if we get something like 2x + 7y = 2/3, then that's not y = mx+b form.

Answer 11

ah okey

Answer 12

You don't have to leave the equation in that form unless instructed to do so. Most books do request that or standard form.

Answer 13

Focus on cranking out this slope right now.

Answer 14

okey
