Would I use the equation y2-y1
m= ------
x2-x1

to find an equation of a line?

Question

Would I use the equation         y2-y1
                                         m=  ------
                                                  x2-x1

to find an equation of a line?

anonymous · Answer

yes. point slope formula

anonymous · Answer

to find the slope of the line.***

anonymous · Answer

so you would find "m" from y = mx+b

anonymous · Answer

Ohhhh so it would be

y-y1 = m(x-x1)

?? Do you happen to know if there is a major difference between those two equations ( One in my question and teh one in this reply?)

anonymous · Answer

gotcha. Thank youuu :)

anonymous · Answer

they are the same equation

anonymous · Answer

divide both sides by (x-x1) and u get the other form

anonymous · Answer

Thats where I got confused :)  Thank yous :)
