In the xy-coordinate system, what is the slope of the line that goes through point (2, 4) and is equidistant from the two points P = (9, 3) and Q = (5, 9)?
Choose the correct choice from the following options:
A) 0.1
B) 0.2
C) 0.3
D) 0.4
E) 0.5
First, get the middle coordinate between (9,3) and (5,9).   x = 9 + (5-9)/2= 
<gadget id="calculator">9 + (5-9)/2</gadget>
<output>7</output>
7   y= 3 + (9-3)/2= 
<gadget id="calculator">3 + (9-3)/2</gadget>
<output>6</output>
6   Second, get the slope of (7,6) and (2,4). m= 6-4 / 7-2 = 2/5= 
<gadget id="calculator">2/5</gadget>
<output>2/5 = around 0.4</output>
0.4   Answer: 0.4
<result>D</result>
