    You have to use the Pythagorean theorem.

    Putting this in the coordinate plane, assuming that the starting point is the origin, the final point would be (-5, 18). Now plug these numbers into the distance formula \(\sqrt{(x2-x1)^2 + (y2-y1)^2}\) and you get the answer.

    @across if i'll join the two end points ..still i am unable to find the distance ...

    If you join the two ends, you will end up with a right triangle that has a base of length 5 and a height of length 15+3.

    |dw:1348069219200:dw| i was doing it this way...and i guess there is no need to plot it on graph and point out coordinates ..... @across thanks alot again

    @erica.d One thing about mathematics is that there are many solution to the same problem. The Distance Formula, for example, is useful when you only know the starting and the ending point (imagine your question, but you're only given 2 points). In this case, using Pythagoras's theorem is like reinventing the wheel.
