Final answer:
To identify the y-intercept, slope, and zero of a linear function, one must look at its equation in the form y = a + bx, where 'a' is the y-intercept, 'b' is the slope, and the zero is found by setting y to zero and solving for 'x'.
Step-by-step explanation:
The y-intercept, slope, and zero of a linear function can be found from its equation. The y-intercept is the point where the line crosses the y-axis and is given by the constant term in the equation, denoted by the letter 'a'. The slope describes the steepness of the line and is indicated by the coefficient of the 'x' term, often represented by the letter 'b'. The zero, also known as the x-intercept, is the value of 'x' when 'y' equals zero; it's the point where the line crosses the x-axis.
Looking at the equation in the form of y = a + bx, the y-intercept is (0, a), the slope is b, and you can find the zero by setting y to zero and solving for 'x'. Therefore, the statement that identifies the y-intercept, slope, and zero for a given linear function must present these elements correctly according to the linear function's equation.
