Find an equation of the line containing the given pair of points.
(1,2) and (3,3)
:
Assign the given coordinates as follows:
x1=1; y1=2
x2=3; y2=3
:
Find the slope (m) using the slope formula: m = %28y2-y1%29%2F%28x2-x1%29
:
m = %283-2%29%2F%283-1%29 = 1%2F2
:
Use the point/slope formula: y - y1 = m(x - x1)
y - 2 = 1%2F2(x - 1)
y - 2 = 1%2F2x - 1%2F2
y = 1%2F2x - 1%2F2 + 2
y = 1%2F2x - 1%2F2 + 4%2F2
y = 1%2F2x + 3%2F2
