I have a 4x4 grid of dots. How do I draw a straight line so I have 8 dots on each side of the line?

Draw it through the middle of the dots.

There is no middle.

If the grid is 4x4, then there is a space between rows 2&3 (or columns 2&3). Draw the line through that space.

To draw a straight line in a 4x4 grid so that there are 8 dots on each side of the line, you need to position the line in a way that divides the grid into two equal halves. Here's one way to do it:

1. Start by drawing a line from the top-left dot to the bottom-left dot. This will create two halves, each with 8 dots.

```
x . . .
x . . .
x . . .
x . . .
```

2. Now draw a line from the bottom-left dot to the bottom-right dot. This will create another line that bisects the grid horizontally into two halves of 8 dots each.

```
x . . .
x . . .
x . . .
x x x x
```

3. Finally, draw a line from the bottom-right dot to the top-right dot. This will complete the division of the grid into two equal halves with 8 dots on each side of the lines.

```
x . . x
x . . x
x . . x
x x x x
```

You can see that by drawing these three lines, you have divided the 4x4 grid into two equal halves with 8 dots on each side of the line.
