Question 1025577
what equation passes through (10,10) & is perpendicular to the line described by y=-1/2x-3? 
slope of given line:: -1/2
----
slope of perpendicular line:: 2
--------------------------------
Form of answer line:: y = mx + b
Solve for "m" and for "b"::
10 = 2*10 + b
b = -10
-----
Ans: y = 2x-10
