Answer:
Yes, it is a linear function
Step-by-step explanation:
The given equation, .8x + 1.5y = -6, is a linear function.
It is in the format of the linear equation Ax + By = C.
In this equation, 0.8 is A, 1.5 is B, and -6 is C.
So, it is a linear function.
yes
Therefore y is an equation of a line with slope 8/15 and y - intercept = 4
I hope this helped you tell me if you need help understanding
Answer: 3.19
So to find the average I used a simple but pretty effective method
3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+8/26=3.1923
So the new average is 3.19
x= -5/6
