<h3>Answer: Choice B) 
</h3>
===================================================
Work Shown:
y = (3/2)x + 4
2y = 3x + 8 .... multiply both sides by 2
0 = 3x + 8 - 2y
3x-2y+8 = 0
The original equation transforms to 3x-2y+8 = 0. It is in the form Ax+By+C = 0. We see that A = 3, B = -2, C = 8. This form is very useful to help find the distance from a point to this line.
The formula we will use is
where A,B,C were the values mentioned earlier. The p,q are the x and y coordinates of the point given. So p = 9 and q = -2
Plugging all that in gives...
