6x - 2y = 10 -2y = -6x + 10...reduce by dividing by -2 y = 3x - 5....slope = 3 and y int = -5
y = 3x + 2 ...slope = 3, y int = 2
These lines are parallel. Parallel lines will have the same slope, but different y int's. There is no solution to this because ur lines never intersect.
How i would solve it is 1. 72.6-35=37.6 2. 37.6/.05=752 and for April you can do the same process phone bill - 35 for usage then divide the answer by .05
