What is the solution of y = 3x + 5 if x = -1/2?

  1. -4

  2. -2

  3. 1

  4. 2

The correct answer is: -4

When solving for a solution, we plug in the given value for x into the equation for y. In this case, we have y = 3(-1/2) + 5, which simplifies to y = -3/2 + 5. This results in y = 3. Therefore, the solution for this equation with x = -1/2 is y = 3. As none of the given choices are 3, we must examine why each one is incorrect A: -4 is incorrect because plugging in x = -1/2 results in y = 3, not -4. B: -2 is incorrect because plugging in x = -1/2 results in y = 3, not -2. C: 1 is incorrect because plugging in x = -1/2 results in y = 3, not 1
