Final answer:
The equation 4y = 12 does not represent a linear equation.
Step-by-step explanation:
The given equation is 4y = 12. To determine which of the statements is not true, we need to analyze the given options. Let's rewrite the equation in slope-intercept form y = mx + b, where m is the slope and b is the y-intercept. By dividing both sides of the equation by 4, we get y = 3. The slope of this line is 0 because the coefficient of x is 0. Therefore, the statement that is not true is that the equation represents a linear equation.
