How would you get the answer r= 18 from the geometry question: find R so that the line passing through (r,3) and (8, -1) has the slope m= 2/5?
You would get the answer r=18 from the geometry question: find R so that the line passing through (r,3) and (8, -1) has the slope m= 2/5 by using the slope formula, which is the change in y over the change in x. The formula allows you to cross multiply and isolate the r variable to solve, which gives you r=18. Thanks for using ChaCha!
