Ok, first off, you are going to have to find the slope.

anonymous · Answer

and i do that how? :D

anonymous · Answer

m = (y2-y1) / (x2-x1)

anonymous · Answer

So, you are going to set the problem up like this...
m = (19-14)/(5-4)

anonymous · Answer

m = 5/1
m = 5

anonymous · Answer

Next, you will use the equation
y-y1=m(x-x1)

anonymous · Answer

why that equation?

anonymous · Answer

y-14=5(x-4)

anonymous · Answer

Because it gives you an equation answer as you ask. 
This kind of equation is known as "point-slope" form.

anonymous · Answer

Your final answer...
y-14=5x-20
y=5x+34
