Emily's watch loses 2 minutes each day. how many seconds per hour?

Given:
2 minutes per day.

1 minute = 60 seconds
2 minutes = 120 seconds

1 day = 24 hours
1 hour = 60 minutes
1 minute = 60 seconds

2 minutes * 60seconds/minute = 120 seconds

In a day, there are 86,400 seconds

1 day * 24 hours/day * 60mins/hour * 60seconds/min = 86,400 seconds

The correct answer is D (3x - 4y = 4)

Explanation:

Let (x1, y1) be (0, -1) and (x2, y2) be (-4, -4).

y - y1 = (y2 - y1)/(x2 - x1) * (x - x1)
y + 1 = (- 4 + 1)/(- 4 - 0) * (x - 0)
y + 1 = (-3)/(-4) * x
y + 1 = (3/4)x
(y + 1) * 4 = 3x
4y + 4 = 3x
4 = 3x - 4y
3x - 4y = 4
