Graphing Tool Grid Display and Snap Behavior

In your graphing questions, you can specify the display and behaviors for each coordinate axis. You can set the minimum and maximum displayed values and the spacing between gridlines and value labels. You can hide gridlines, labels, or coordinate axes. And you can configure the snap spacing, which determines how objects drawn on the graphing tool are positioned relative to the coordinate grid when they "snap" to the nearest specified unit.

To configure the grid display and snap behavior for the graphing tool, you can add any of the following notation to the answer line, delimiting each item with a semicolon. For example, to set the minimum and maximum values displayed for the graph of a linear equation, your answer key could be:

Examples

line: y=x+1; axes: [0, 30, 0, 30]

Spacing values must be positive decimal numbers; minimum and maximum values for axes must be decimal numbers, and the maximum must be greater than the minimum.

Example

Set the maximum and minimum values displayed on the grid.

axes: [x_minimum, 
x_maximum, y_minimum, 
y_maximum]

-10, 10, -10, 10

axes: [0, 30, 0, 30]
