Since the origin lies at the point (0, 0), you can find the distance from a point to the origin by entering the coordinates for the point and the coordinates for the origin into the distance formula and solve. So, the formula to calculate the distance from a point to the origin becomes: d=\\sqrt{\\left ( x_{2}-0 \\right ) ^{2} + \\left ( y_{2}-0 \\right ) ^{2}} d=\\sqrt{x^{2} + y^{2}} The distance from a point to the origin is equal to the square root of the point’s x coordinate squared plus the y coordinate squared. The line connecting the origin to the point forms the hypotenuse of a right triangle, the x-axis forms one side, and the line connecting the point to the x-axis forms the other side. So, the formula to calculate the distance from the point to the origin is the same formula used to calculate the length of a right triangle’s hypotenuse. Great job if you noticed that the formula above looked strikingly similar to the Pythagorean theorem because these formulas are one and the same.
