An interior designer made a scale model of a room. Each 1 inch in the model represented 12 feet in the actual 1 room. If the length of a hall was 2 inches in the model, what was the actual length of the hall?

perpendicular: -1/7x; parallel: 7x

Step-by-step explanation:

So the only blanks that we need to fill in is the slope. The given slope is 7. a line parallel to the given would have the same slope so we answer 7x. for perpendicular, the slope is reciprocal and change the signs. taking the given slope of 7 we must change the sign from positive to negative and use the reciprocal (7/1>1/7). our answer for perpendicular is -1/7x
