Question

Determine the value of "r" so the line that passes through each pair of points has the given slope (m).

(6,8), (r,-2), m = -3

Answer 1

Hint:

Solve

(-2-8)/(r - 6) = -3

for r

Answer 2

Ok so I have -10 / r-6 = -3. So r-6 has to equal one third of 10 for the fraction to work out to -3, so does that mean the answer is r = 9.333333333...?

Answer 3

sry the website wouldn't load, but it seems to be working now

Answer 4

yes r = 9.3333, but I would keep it in fraction form

so r = 28/3

Answer 5

Ok thanks!
