Directions = Write in point-slope form an equation of the line through each pair of points. #1. (-10,3) and (-2,-5) Can anyone show me how to do this?
@digitalcamera do you know how to write a equation of line if two points are given ?
yes
tell me
I think I do anyways..I have a problem I did the other day in class. I don't know if it's the same directions though, one second, I'll type it up from my notebook
u can do this by using 2point formula. (y2-y1)/(x2-x1) =(3+5)/(-10+2) =8/-8 slope=-1 y-y1=slope(x-x1) y+5=(-1)(x+2) y+5=-x-2 y+x+7=0
Remember :- If two points are given,then your first preference is to find SLOPE.
Find an equation of a line that passes through (3,2) (5,8) label x1 y1, x2, y2 y-2=3(x-3) distribute y-2=3x-9 +2 +2 y=3x-7
is the first problem asking for the same thing?
\[\large \bf slope=\frac{y_2-y_1}{x_2-x_1}\] where, x1,y1,x2 and y2 are co ordinates
i dont know what "write in point slope form an equation of the line through each pair of points" means
yaa its asking for same..@digitalcamera
like in this problem "- \[\large \bf slope=\frac{-5-3}{-2+10}=\frac{-8}{8}=-1\]
can you just do the first one for me so i can understand how to do the rest? this is confusing me
any confusions in my step ?
no :)
u can check my solution..
