Question

What is the standard form equation of the line passing through (5,-3) with a slope of -3

Answer 1

the line is y +3 = -3(x - 5)

expanding gives

y + 3 = -3x + 25

standard form is

ax + by + c = 0

just rewrite the above equation

Answer 2

another way is y=mx+b
-3=5*-3+b

sovling for b you get b=12

so -3= 5*-3+12

y=x*-3+12

y-x*-3=12

Answer 3

Thanks Tim that is one of the answers thanks alot

Answer 4

@campbell_st, @timo86m I strongly feel you should refrain from giving complete answers. I think the formula is more sufficient than enough

\[y - y_1 = {(y_2 - y_1) \over (x_2-x_1)} (x-x_1)\]

where (x_1, y_1)-->point 1 on the line
(x_2, y_2)-->point 2 on the line

Now he should have solved it.
I am saying this based on Openstudy Guidelines. Make sure you have a check at them

Answer 5

IDK if we gave complete answers. she can mess around with the equation if she want to make it equal 0 or have a constant on rhs

Answer 6

Well, then in that case @timo86m , you never ever made mistake while learning for the first time.??Our duty must be to teach and not give complete answers

Answer 7

well depending on the person. I like to learn by having the answer then work on my own to reach that answer :)

Answer 8

Ok . Let @Directrix have his say

Answer 9

depends on attitude of person. If they want the answer for easy grade and never learning anything then thhat is bad. But to have the answer as a guide to check if your work is right then that is good.

Answer 10

@Vanessa173

From above in thread:
>standard form is
ax + by + c = 0
^^ is incorrect

You may want to recheck your answer options in light of the following:

Standard Form for Linear Equation

Standard Form: the standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers.

Answer 11

@timo86m , agree to your point of view but @Vanessa173 was only interested in the final answer as I can see from her statements So basically, we are bunch of people who are answering (probably) giving her answer out for the test :P

Answer 12

@Directrix , agreed :D

Answer 13

lol very rarely are there take home test. Probably only on online classes but i bet the are timed and waiting here for an answer would suck.

Answer 14

LOL, idk . as far as I know we shouldn't be giving answers to the people here as the moderators will serve you with a warning here. Have a look at Open study guide lines. I have also got warned once. So that's why alerting you.
