Question 13 What is the $x$-intercept of the line: \[ 2 x-3 y=-16 \]

Step 1 ：The equation of the line is \(2x - 3y = -16\).

Step 2 ：Set \(y = 0\) to find the x-intercept, the equation becomes \(2x = -16\).

Step 3 ：Solve for \(x\) to find the x-intercept.

Step 4 ：\(x = -16 / 2\).

Step 5 ：So, \(x = -8\).

Step 6 ：Final Answer: The \(x\)-intercept of the line is \(\boxed{-8}\).
