Perpendicular to 3x-6y=-2 containing points (-3,-8)
72 degrees is your answer
13 is not the same as 1/3! the division symbol is not a symbol used to connect two numbers, it is used to find their quotient. for example, 6/2 would be like saying: you have 6 cookies, and 2 friends. how many cookies does each friend get? the answer is obviously not 62, it is 3! so, the exact quotient is 0.3 repeating. you could memorize this or use the fact that 0.9 repeating is 1.
