Question 414219
Write an equation in standard form of the line passing through (2,-5) and       (-4,7) Thanks. Please answer ASAP for I have a test on monday.

(2,-5) and       (-4,7) 

The slope of line passing through (x1,y1),(x2,y2) = (y2-y1)/(x2-x1)
m=7-(-5)/(-4-2)
m=12/-6
m=-2
...
y= mx +b .
take any point above
(2,-5)
plug the point and slope to find b
-5=-2*2+b
-5+4=b
b=-1
so the equation is
y=-2x-1
