Still a little confused on what equation to use and how to figure this out! Any one please help me out?
Find the slope of a line that passes through the points (2, –3) and (–1, 4).

first solve for the slope then use the y-intercept form to get the equation
OpenStudy (nincompoop):
do you know how to solve for the slope @SleepEatRugby
OpenStudy (the_fizicx99):
M = y2 - y1/X2 - x1
OpenStudy (sweetburger):
use point slope
OpenStudy (nincompoop):
@sweetburger @tHe_FiZiCx99 I got this... you two can calm down

point slope form i tell you
OpenStudy (the_fizicx99):
@nincompoop oki :(
OpenStudy (nincompoop):
@SleepEatRugby you need to respond
OpenStudy (anonymous):
I keep getting a negative number as the denominator for the slope would this be wrong?
OpenStudy (nincompoop):
show me how you are solving for the slope

(4 - -3)/2 + (-1 - 2)/2
OpenStudy (nincompoop):
\[slope=m=\frac{ rise }{ run }=\frac{ \Delta y }{ \Delta x }=\frac{ y_2-y_1 }{ x_2-x_1 }=\frac{ 4-(-3) }{ -1-2 }\]
OpenStudy (nincompoop):
where are you getting the denominator 2? I think your mixing up mid-point and slope formulas
OpenStudy (nincompoop):
then whatever your m (slope) is plug it into the point-slope form
\[y-y_1=m(x-x_1)\]
use either (2, -3) or (-1, -4) as your x1 and y1
OpenStudy (nincompoop):
are you still there?
