For the function y=400-22x, what is the rate of change
1 answer:
Answer:
-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.
