Answer:
Slope
Explanation:
Since, the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line is called slope of the line,
That is, slope shows the rate of change between two points in the graph,
If
and
are two points from which a line passes,
Then the rate of change of the line or slope of the line is,

Also, change is y coordinates is called rise while the change in x -coordinates is called run.
Hence, the missing word in the given statement is Slope.
