To find the equation of the line, you
need to determine the slope of the line. To do this, use
the slope formula. This will give you,

m = ( y_{2}  y_{1} ) / ( x_{2}  x_{1} )
m = ( 4  5 ) / ( 14  12 )
m = 1/2 

.Now that you have the slope of the
line, plug it and a point on the line into the
slopeintercept formula and solve for b.

y = mx + b
y = ( 1/2 )x + b
( 5 ) = ( 1/2 )( 12 ) + b
5 + 6 = b
b = 11 

Finally, plug in your values of m
and b into the slopeintercept formula.
Therefore, your final answer will be,
