In P5.js, the y-axis is: Vertical and Increases upwards Horizontal and increases to the left Horizontal and increases to the right Vertical and increases downwards

## Step 1<br />In the P5.js programming environment, the y-axis is vertical. This is a standard convention in most graphical systems, where the y-axis is typically vertical.<br /><br />## Step 2<br />The y-axis increases upwards. This is a common convention in most graphical systems, where the y-axis increases as you move upwards.<br /><br />## Step 3<br />The other options are incorrect because they either describe the y-axis as horizontal or they describe the direction of increase as downwards or to the left or right.
