Find an equation of the line containing the given pair of points.
(3, 2), and (8,5)
The equation of the line in slopeintercept form is y= what

Well, there are several ways but you want y = m x + b
so
2 = m (3) + b
b = (3 m2) use (3m2) for b in the other point
5 = m (8) + b
5 = 8 m + 3 m  2
5 m = 3
m = 3/5
then b = 3 (3/5)  2
b = 9/5  10/5 = 1/5
so
y = (3/5) x  1/5
or
5 y = 3 x  1
