help please anyone

OpenStudy (anonymous):

Launch Area:___(1, 2)___ Point A:___(0, 3)___ Point B:___(-3, 0)___ Point C:___(-1, -4)___ Determine the equation of the line, in point-slope form, that will get your spacecraft from Point A to Point B.

@phi @kobeni-chan

OpenStudy (anonymous):

sry for tagging you so much this is my last one

OpenStudy (kobeni-chan):

Lol its k Sp Point A is (0,3) and Point B is (-3,0) Use the slope formula to find the slope (y-y/x-x)

OpenStudy (kobeni-chan):

This would be (3-0)/(0+3) <---(subtraction and negative sign cancel each other out)

OpenStudy (anonymous):

slope is 1 y intercept 3 x intercept-3 and there is no curvature

OpenStudy (kobeni-chan):

those are correct. Now you use one set of coordinates and the slope to fill in point slope form. y-(insert y variable)=m(x-(insert x variable))

OpenStudy (anonymous):

so (3-0)/(0+3) would solve question

OpenStudy (anonymous):

ok one sec

OpenStudy (anonymous):

y-3=m-3

OpenStudy (anonymous):

idk if that looks correct

OpenStudy (phi):

y - y0 = m(x - x0) m is 1 you left out the "x"

OpenStudy (anonymous):

oh i almost got it :/

OpenStudy (kobeni-chan):

yes, and you're picking one set of coordinates, so its either (0,3) or (-3,0), so there will be a zero somewhere

OpenStudy (anonymous):

do you mean by a zero inside the parentheses

OpenStudy (anonymous):

sry for the trouble im not the smartest

OpenStudy (anonymous):

as you can tell

OpenStudy (kobeni-chan):

aww :c that's not a problem It will either be y - 3 = 1 (x - 0) or y - 0 = 1 (x + 3) depending on which one you want to use After you pick one, you can simplify it but I don't think you necessarily need to

OpenStudy (anonymous):

ok thx
