How many points will be equal distant from 2 parellel lines 3" apart & also be 2" from a single point laying on one those 2 parellel lines?

You should have a sketch to help you. Have you done so? The locus between the parallel lines is a line equidistant from the parallel lines. Then the locus from a point is a circle with radius 2". Where the circumference of your circle locus and the locus line meet, you have the points you need. Now, you need to count the number of points you obtained.
