To find this answer you need to know 2 things.
1) how to calculate the slope of a line given two points on that line
2) the relationship between the slopes of lines that are perpendicular to each other.
To fine the slope given two points:
m+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
You have the two points, you do the math
To find the slope of a line that is perpendicular to a line with a given slope, you need to know that the slopes of those lines result in a product of -1
m%2Am%5Bp%5D+=+-1+ where m[p] is the slope of the perpendicular line
That ought to get you there!
