Given that a certain insect beat its wings 250 times per second .
Let ' x ' denote the time in seconds .
Let ' y ' denote the insect beats its wings times per second .
General form of equation in slope intercept form is
y = m x + b
where ' m ' is slope and ' b ' is intercept .
As the insect beat its wing 250 times per second .
We know that slope denotes the change per second .
Thus we have slope , m = 250 .
' b ' denotes the y - intercept .
Here b = 0 .
Thus the equation that represent this situation become
y = 250 x + 0 or we can rewrite it as y = 250 x
Relationship between flying time in second and number of times insect beat its wing is
y = 250 x .
