Question

1. (17, -13), (17, 8)

Explanation:

Assuming the problem is to find the distance between the two points \((17, -13)\) and \((17, 8)\):

Step 1: Recall the distance formula for vertical lines

For two points \((x, y_1)\) and \((x, y_2)\) (where the \(x\)-coordinates are the same), the distance \(d\) is given by \(|y_2 - y_1|\).

Step 2: Substitute the values

Here, \(x = 17\), \(y_1 = -13\), and \(y_2 = 8\). So we calculate \(|8 - (-13)|\).

Step 3: Simplify the expression

\(8 - (-13)=8 + 13 = 21\), and the absolute value of \(21\) is \(21\).

Answer:

The distance between the two points is \(21\).
