Hello ther is a solution : x+3y = -9 3y =-x-9 y = (-1/3)x-3 1 ) <span>the slope of a line parallel to this line is : (-1/3) 2 ) let ' a ' </span>the slope of a line perpendicular a line: x+3y = -9 I'have (-1/3)× a = -1 a = 3
The answer would be 6 1/4 because you have to change the 1/2 into 2/4,then you subtract that to 1/4 which is 1/4,Then subtract 7 and 1.Then you would come up with the answer 6 1/4
