Choose the equation below that represents the line passing through the point (-5, 1) with a slope of 3/2.

y - 5 = 3/2(x + 1)

y + 1 = 3/2(x - 5)

y + 5 = 3/2(x - 1)

y - 1 = 3/2(x + 5)

Question

Choose the equation below that represents the line passing through the point (-5, 1) with a slope of 3/2. 

 y - 5 =  3/2(x + 1) 

 y + 1 = 3/2(x - 5) 

 y + 5 = 3/2(x - 1) 

 y - 1 =  3/2(x + 5)

point slope form: y - y1 = m(x - x1)
when m = slope and given the point (x1, y1)

anonymous · Answer

I'm guessing D or C

anonymous · Answer

use this eq..

(y-y1)=m(x-x1)

m=slope..compare your choice by putting values int is eq you will get result..

jigglypuff314 · Answer

(-5, 1)  as  (x1, y1)
into y - y1 = m(x - x1)
you're close :)

anonymous · Answer

ok but dont you mean y^1 and x^1

jigglypuff314 · Answer

ah no sorry for the confusion
I mean  $y_1~~ and~~x_1$  subscripts

jigglypuff314 · Answer

it is to tell the difference between  y and  $y_1$
y - $y_1$ = m(x - $x_1$)
plug in  (-5, 1)  as  ($x_1$, $y_1$)
that better?

anonymous · Answer

im not thinking at all today, this is what im writing

(-51, 11)  -_-

anonymous · Answer

i know im wrong, lol

jigglypuff314 · Answer

lol xD
y - (1) = m ( x - (-5))   is what I meant :P

anonymous · Answer

oh wait i think i understand a bit better, 

is that it? or is there more to it?

jigglypuff314 · Answer

well you're gonna have to choose the letter that matches it right? ;)
and negative times a negative makes a positive

anonymous · Answer

oh ok, thanks!
