What number is ** plural( abs( DISTANCE ), "position") to the leftright of the orange dot**? The distance between tick marks is 1.

What number does the orange dot represent? The distance between tick marks is 1.

init({
range: [ [ MIDPOINT-6, MIDPOINT+6 ], [ -1, 1 ] ]
});
line( [ MIDPOINT-5, 0 ], [ MIDPOINT+5, 0 ] );
for ( var x = MIDPOINT-5; x <= MIDPOINT+5; x++ ) {
line( [ x, -0.2 ], [ x, 0.2 ] );
}
style({ stroke: "#6495ED", strokeWidth: 3.5 });
line( [ MIDPOINT, -0.2], [MIDPOINT, 0.2]);
label( [ MIDPOINT, -0.53 ], MIDPOINT, "center", { color: "#6495ED" });
style({ stroke: "#FFA500", fill: "#FFA500" });
graph.orangeDot = circle( [ NUMBER, 0 ], 0.10 );

We know where

is on this number line because it is labeled.`MIDPOINT`

Numbers to the left are less than

, while numbers to the right are greater than `MIDPOINT`

.`MIDPOINT`

We need to find the number represented by the blue dot, which is `plural( abs( DISTANCE ), "position")` to the leftright of the orange dot.

style({ stroke: "#6495ED", fill: "#6495ED" });
graph.blueDot = circle( [ NUMBER+DISTANCE, 0 ], 0.10 );

Starting from

, we move `MIDPOINT`

to the leftright to reach the blueorange dot.`abs( NUMBER-MIDPOINT+DISTANCE )`

var color = "#6495ED";
if ( DISTANCE === 0 ) {
color = "#FFA500";
}
style({ stroke: color, fill: color, strokeWidth: 3.5, arrows: "->" });
line( [ MIDPOINT, 0 ], [ NUMBER+DISTANCE, 0 ] );
graph.blueDot.toFront();
graph.orangeDot.toFront();

Thus, the blueorange dot represents the number

.`NUMBER+DISTANCE`

var color = "#6495ED";
if ( DISTANCE === 0 ) {
color = "#FFA500";
}
label( [ NUMBER+DISTANCE, -0.53 ], NUMBER+DISTANCE, "center", { color: color });
