Answer:
Rate of change = 250.
Katie's salary is increasing $250 per week.
Step-by-step explanation:
Let x be the number of weeks.
We have been given that Katie is just hired at a new sales company. She is given a $500 hiring bonus.This means that initial value or y-intercept is 500.
Additionally she earns an average commission of $250 per week. So the commission after w weeks will be 250*x.
Upon using our given information we can form an equation as: [tex]y=250x+500[/tex]
Since we know that an equation of line in slope-intercept form is: [tex]y=mx+b[/tex], where,
m = Slope or rate of change.
b = The y-intercept.
Upon comparing our equation with slope-intercept form of equation we can see that rate of change for Katie's salary is 250, which means Katie's salary is increasing $250 per week.
