What are trend lines?

A trend line is like drawing a straight path that shows where something is going, up, down, or staying steady.

Imagine you're playing with your toy car on a ramp. If the ramp goes up, your car moves higher; if it goes down, your car zooms faster. A trend line is like imagining that ramp, it helps you see if things are getting better, worse, or just staying the same over time.

Think of a trend line as a special kind of ruler. You put it on a graph (like a picture showing how something changes), and it shows the general direction of the points. If most of the points are going up, your trend line will go up, like your toy car climbing a hill.

People use trend lines to make predictions. Maybe you're tracking how many cookies you eat each day. A trend line could show if you're eating more, less, or just the same number of cookies every week, helping you decide whether to keep counting or start a cookie challenge!
