In the xy-coordinate system, what is the slope of the line that goes through the origin and is equidistant from the two points P = (4, 6) and Q = (6, 2)?  Choose the correct answer.
A) 0.8  B) 1.0  C) 1.2  D) 1.4  E) 1.6
First, get the middle coordinate between (4,6) and (6,2).   x = 4 + (6-4)/2= 
<gadget id="calculator">4 + (6-4)/2</gadget>
<output>5</output>
5   y= 2 + (6-2)/2= 
<gadget id="calculator">2 + (6-2)/2</gadget>
<output>4</output>
4   Second, get the slope of (5,4) and (0,0). m= 4-0 / 5-0= 
<gadget id="calculator">4-0 / 5-0</gadget>
<output>4</output>
4/5= 
<gadget id="calculator">4/5</gadget>
<output>4/5 = around 0.8</output>
0.8   0.8nswer: 0.8
<result>A</result>
