"text": "Let\u2019s look at an example to see how this works. Suppose you plant a seed and measure the plant\u2019s height every day to see how much it grows. Each day, the plant grows a little taller. That means the height of the plant depends on the passing of time.",

{
"text": "The plant gets taller as more time passes \u2014 that\u2019s why time is the independent variable. You can show this using a math equation.",

},
{
"text": "Use the letter h for the plant's height, and t for time in days. If the plant grows 2 centimeters each day, you can write: h = 2 \u00d7 t. That means the height is 2 times the number of days the plant has been growing.",
"latex": "h = 2 \\times t"
},
{
"text": "You can also show this with a graph. Time, t, goes on the bottom line \u2014 that\u2019s called the horizontal axis. Height, h, goes on the side \u2014 that\u2019s the vertical axis.",

{
"text": "In graphs, the independent variable goes sideways, and the dependent variable goes up and down. The line goes up, because the plant keeps getting taller over time.",
