Step-by-step explanation:
Y - 3 = 5/3 (x - 0)
this is point slope
y - 3 = 5/3x
y = 5/3x + 3
Answer:
You can conclude that the lines are perpendicular, and will cross at exactly one point.
Step-by-step explanation: If one line has a zero slope, and the other's slope is undefined, that means one line is exactly vertical, and the other is exactly horizontal. This means that they will cross at exactly one point, and are perpendicular.
Since Timothy collected more, we take the amount Timothy collected and subtract the amount Eric collected from that.

That means Timothy collected .5 kilograms more candy than Eric.
