Use the definition of slope,
m=%283-h%29%2F%28-9-%28-8%29%29=7
%283-h%29%2F%28-9%2B8%29=7
%283-h%29%2F%28-1%29=7
3-h=-1
Solve for h.

Use the point-slope formula
+%28+h+-+3+%29+%2F+%28+-8+-%28-9%29+%29+=+7+
+%28+h+-+3+%29+%2F+%28+-8+%2B+9+%29+=+7+
+h+-+3+=+7+
+h+=+10+
-----------------
check:
+%28+h+-+3+%29+%2F+%28+-8+-%28-9%29+%29+=+7+
+%28+10+-+3+%29+%2F+%28+-8+-%28-9%29+%29+=+7+
+7+%2F+1+=+7+
+7+=+7+
OK
