    -22

    Step-by-step explanation:

    The function y=400-22x is a linear equation in the form y=mx + b. Although they put "mx" after "b" so the equation doesn't start with a negative.

    "m" is rate of change, or the slope if graphed.

    The negative means "y" decreases as "x" increases. On a graph, it decreases left to right.
