Question

i know how to find the slope of line, although how do you do it when the lines do NOT have given points(dots) on them? please help fast, test tommorow :)

Answer 1

if line is given in the form of ax+by+c=0
y=(-a/b)x-c/b
compare this to slandered equation y=mx+c
m=slope=-a/b

Answer 2

thanks so much you explained that better than my math teacher!
