Answer:
3y = -6x - 15
Step-by-step explanation:
To put 6x + 3y = -15 into Slope Intercept Form you need to know the formula (y = mx + b) so we know we need to get y on its own side so we can -6x from both side giving us 3y = -6x +-15 or 3y = -6x - 15 There are many different slope intercept forms for this equation depending on how you get y by its self!

We have 1.5 hours 30 minutes = 120 minutes;
1 hour 15 minutes = 75 minutes;
1.25 minutes = 85 minutes;
75 < 85 < 120
The median is 85 minutes.
Finally, 1 hour 15 minutes is the median.
At least 4 means its minimum value is 4 so n≥4
