What is that called? @telltoamit

anonymous · Answer

@telltoamit   So   4/-6 ? Is that correct ?

anonymous · Answer

Thats my slope?

anonymous · Answer

yepp. jus plug in the values

directrix · Answer

(1,-8) and (-5,-4)
Think of slope of a line as rise over run or as change in y over change in x.

slope= [ (-4) - (-8)] / [(-5) - (1)] = (4)/(-6) = - 2/3

Thank you!!! @Directrix @telltoamit  @Directrix  -2/3 thats because I have to simplify right?

After you learn the slope concept, you may want to check out the online slope calculator at the following link: http://www.basic-mathematics.com/slope-calculator.html

directrix · Answer

Yes. -4/6 reduces to -2/3 because -2 and 6 both have a common factor of 2.
