Answer: -4/5
Step-by-step explanation: To find the coefficient of y in the equation 3y² - ⅘y + 6 = 0, we need to identify the term in the equation that contains y and then extract the coefficient.
In this equation, the term that contains y is -⅘y. The coefficient of y is the number that is multiplied by y in this term, which is -⅘.
Therefore, the coefficient of y in the equation 3y² - ⅘y + 6 = 0 is -⅘.
