An optometrist is designing an eye test using dilation with a scale factor on a coordinate plane with the origin as the center of dilation. The first coordinate point on the eye test is ( 18 , 39 ) (18,39). The optometrist uses a scale factor of 1 3 13 to create the second point on the eye test. Write the coordinates of the new point in the form ( a , b ) (a, b).
