What is the slope of the line that passes through points (1,2) and (3,5)

2/3

3/2

-2/3

-1/2

y - 3 = -2 (x - 1 )

y - 3 = 1/2 (x - 1 )

y - 1 = -2 (x - 3 )

y - 1 = -1/2 (x - 3 )

what is the slope of the perpendicular line  y=1/2x  that passes through point 1,3

y - 3 = -2 (x - 1 )

y - 3 = 1/2 (x - 1 )

y - 1 = -2 (x - 3 )

y - 1 = -1/2 (x - 3 )
