Final answer:
To find the zero of the linear function, we need to solve the equation 3x - 45 = 0. The zero of the linear function is x = 15.
Step-by-step explanation:
To find the zero of the linear function, we need to solve the equation 3x - 45 = 0.
First, we add 45 to both sides of the equation to isolate the variable: 3x = 45.
Then, we divide both sides by 3 to solve for x: x = 15.
Therefore, the zero of the linear function is x = 15.
