(y-2)/(x-3) = (7-2)/(9-3)
y-2 = 5/6 (x-3)
y-2 = 5/6 (x-3)

First, find the slope using the formula y2-y1/x2-x1.
7 - 2/9 - 3
5 / 6---> slope
Use point-slope form: y - y1 = m (x - x1)
Use any one point:
y - 2 = 5/6 (x - 3)
Distributive property:
y - 2 = 5/6x - 15/6
Add 2 to each side:
y = 5/6x - 15/6 + 2/1
y = 5/6x - 1/2
7 - 2/9 - 3
5 / 6---> slope
Use point-slope form: y - y1 = m (x - x1)
Use any one point:
y - 2 = 5/6 (x - 3)
Distributive property:
y - 2 = 5/6x - 15/6
Add 2 to each side:
y = 5/6x - 15/6 + 2/1
y = 5/6x - 1/2
