Step-by-step explanation:
the easy formula is rise/run. If you find the two points where it perfectly intercepts the graph you could up 1 unit and right 5, or down 1 unit and left 5, both leaving you with 1/5
3x + 2y + 1 = 0
subtract 3x+1 from each side
3x + 2y + 1 - 3x -1= -3x -1
2y = -3x-1
divide by 2 on each side
2y/2 = -3x/2 -1/2
y = -3/2 x -1/2
this is in the form y = mx +b where m is the slope
m = -3/2
the slope is -3/2

1. From the first floor to the 4th floor is a distance of 3 floors. From the first floor to the 16th floor is a distance of 15 floors, a distance that is 5 times as far as the first trip. We expect the second trip to take 5 times as long, or ...
(4 s) × 5 = 20 s
___
2. The smallest and largest ratio number sum to 2+7=9. That sum exceeds twice the remaining ratio number by 9-2×3 = 3. Since this difference represents a difference of 30, each of the original numbers must be 30/3 = 10 times its corresponding ratio number.
The three numbers are 7×10 = 70, 3×10 = 30, and 2×10 = 20.
<em>Check</em>
(70 +20) -2×30 = 30 . . . true
