Simple...
you have

and

Just subtract...but first find a common denominator...
Use 40 as the common denominator...

and

So, subtract,

=

Thus, your answer.
So we are given two points, say P1(4,7), P2(x,19).
Slope is given by
m=3=(y2-y1)/(x2-x1)=(19-7)/(x-4)
solve for x
3=(19-7)/(x-4)
cross multiply
3(x-4)=12
3x-12=12
3x=12+12=24
x=8
Answer:
1/5(9times) would be your answer man!!!
