Question

what is the equation for slope? the one for (x,y) values?

Answer 1

(y-y1)=m(x-x1) for point(x1,y1) and slope m

Answer 2

thanks

Answer 3

@madrockz I think that's point-slope form
Finding slope is:
\[\LARGE m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]

Answer 4

thanks:) so much

Answer 5

Anytime :)
