If `6 ge x ge -2` and `4 ge y ge -4`, find the limits for `(y)/(x)`, where x and y are non-zero integers.

A

`(y)/(x) ge 2, (y)/(x) le (2)/(3)`

B

`(y)/(x) ge (-2)/(3), (y)/(x) le 2`

C

`(y)/(x) ge (-2)/(3), (y)/(x) le (1)/(4)`

D

`(y)/(x) ge -4, (y)/(x) le 4`

The correct Answer is:
To find the limits for \(\frac{y}{x}\) given the inequalities \(6 \geq x \geq -2\) and \(4 \geq y \geq -4\), we will analyze the possible values for \(x\) and \(y\) and compute the limits for the ratio \(\frac{y}{x}\). ### Step 1: Identify the ranges for \(x\) and \(y\) - The values of \(x\) can range from \(-2\) to \(6\) (inclusive). - The values of \(y\) can range from \(-4\) to \(4\) (inclusive). ### Step 2: Consider the non-zero integer constraints Since \(x\) and \(y\) must be non-zero integers, we can list the possible values: - Possible values for \(x\): \(-1, 1, 2, 3, 4, 5, 6\) - Possible values for \(y\): \(-3, -2, -1, 1, 2, 3, 4\) ### Step 3: Calculate the limits for \(\frac{y}{x}\) We will calculate \(\frac{y}{x}\) for the extreme values of \(y\) and \(x\). 1. **Maximum value of \(\frac{y}{x}\)**: - To maximize \(\frac{y}{x}\), we need the maximum \(y\) and the minimum positive \(x\). - Maximum \(y = 4\) and minimum positive \(x = 1\): \[ \frac{y}{x} = \frac{4}{1} = 4 \] 2. **Minimum value of \(\frac{y}{x}\)**: - To minimize \(\frac{y}{x}\), we need the minimum \(y\) and the maximum positive \(x\). - Minimum \(y = -4\) and maximum \(x = 6\): \[ \frac{y}{x} = \frac{-4}{6} = -\frac{2}{3} \] 3. **Consider negative values of \(x\)**: - If \(x = -1\) and \(y = 4\): \[ \frac{y}{x} = \frac{4}{-1} = -4 \] - If \(x = -2\) and \(y = 4\): \[ \frac{y}{x} = \frac{4}{-2} = -2 \] - If \(x = -1\) and \(y = -4\): \[ \frac{y}{x} = \frac{-4}{-1} = 4 \] ### Step 4: Compile the results From the calculations: - The maximum value of \(\frac{y}{x}\) is \(4\). - The minimum value of \(\frac{y}{x}\) is \(-4\). Thus, the limits for \(\frac{y}{x}\) are: \[ -4 \leq \frac{y}{x} \leq 4 \] ### Final Answer: The limits for \(\frac{y}{x}\) are \(-4 \leq \frac{y}{x} \leq 4\).
