# Labels

By adding a point to the expression list, you'll automatically have the option to add a label. Enabling the checkbox without adding text will automatically show the coordinates of the point on the graph paper.

To create a text label, make sure the "Show Label" checkbox is enabled and type in the text of your choice. The graph paper will automatically update. It's also possible to create labels on movable points

Dynamic Labels

If a parameter is already defined in the calculator, then the value of that variable can be used to create dynamic labeling. For example, if m and b are defined in the calculator, then typing ${m} and/or${b} in any point label text areas will display the numerical values of m and b. The label will automatically update as the value of m or b changes and can be used with text to great effect. Below, we've used y = ${m}x +${b} as a point label in order to display the equation of the line in slope-intercept form as the sliders are moved.

It's also possible to add formatted math text using back-ticks. This can be combined with dynamic labels to display equations on the graph paper.

Prossi:

Is there a way I can have fractions in the latex parser for labels? I tried using frac{ and it didn't seem to work, I was hoping Desmos had its own way of doing it

John Bennett:

@Prossi

It appears you need to add a ` (back tick, usually beside the 1 at the top of the keyboard) and then type in the Latex. I was also able to add variables of the \${a} to use sliders to move the point with the label.

Me:

Make sure it's like \frac{a}{b}, not frac{a}{b}
