Problema Solution
determine the value of r so the line that passes through each pair of points has a given slope
(6,3), (r,2), m=1/2
Answer provided by our tutors
the slope is equal to m, which is the change in y-values/the change in x-values of 2 points on a line
since m=1/2, you have
1/2 = (2-3)/(r-6)
1/2 = 1/r-6
you need r-6 to equal to
so r-6=2
r = 8
the value of r to make this true is 8
