Choose the equations below that are perpendicular.
1. y = 7x+5
1
II. y +4 =-* (x + 7)
III. y = -7x-7
O None of the lines shown are perpendicular to each other.
O I and III are perpendicular because their slopes are opposites.
O II and III are perpendicular because their slopes are reciprocals.
O I and II are perpendicular because their slopes are opposite reciprocals.
If i think this is what your asking, he should look at the grams or pounds/ounces and compare the to their cost then max can identify which one is proportional and which is not ( i think xd)
