Set 5: Linear Functions (Intermediate)

Choice A is correct. Choice A is the correct answer. Set $y=0$. 1. Substitute: $0= \frac{1}{2}x - 3$. 2. Add 3: $3= \frac{1}{2}x$. 3. Multiply by 2: $6= x$. Strategic Tip: To clear the fraction, multiply the entire equation by the denominator. Choice B is incorrect because it is the y-intercept. Choice C is incorrect because it misses the multiplication step. Choice D is incorrect because of sign error.
