Given the graph y = 4/3x - 2, what is the value of x when y = 4?

  1. 3

  2. 4

  3. 6

  4. 8

The correct answer is: 6

To solve this problem, we need to substitute the given value of y=4 into the equation and solve for x. Doing so, we get 4 = 4/3x - 2 Adding 2 to both sides, we get: 6 = 4/3x Dividing both sides by 4/3, we get: 6 / (4/3) = x Multiplying by the reciprocal, we get: 6 * (3/4) = x Simplifying, we get: 4.5 = x Therefore, when y = 4, the value of x is 4.5, which is not listed as an option. Option A (3) and B (4) both produce y values that are less than 4, so they cannot be the correct value of x
