The equation given in the question is
2x - 3y = 6
Dividing both sides of the equation by 3, we get
2/3 x - y = 2
y = 2/3 x - 2
Then, from the above equation we can tell that the slope of the line in the graph is 2/3. The slope of a line perpendicular to this slope will be - 3/2. The line also contains the points (-2,-3).
Then, the equation of the perpendicular line will be
y = mx + b
- 3 = (- 3/2)(- 2) + b
- 3 = 3 + b
b = - 6
Then
y = (-3/2)x - 6
y + 6 = (- 3/2)x
2y + 12 = - 3x
3x + 2y = - 12
Biased estimators are Sample median & sample standard deviation
Unbiased are sample mean sample variance and sample proportion
Neither choice include population mean, standard deviation proportion and variance

Answer:
87,600 minutes
Step-by-step explanation:
Given that practice time by Jonas :
1 hour per day for 2 years :
Bradley practices : 2 hours a day more than Jonas,
How many more minutes does Bradley practice the guitar than Jonas over the course of 2 years
Number of days in a year = 365 days
2 hours per day for (2 * 365) days :
2 * (2 * 365) = 1460 hours
Recall :
60 minutes = 1 hour
(60 * 1460) = 87,600 minutes
