What is the slope of the function that was used to generate the t-chart shown?

Hint: Slope is the m = change in y/change in x = ( ^y₂^-y₁) / (^x₂^-x₁)

• b = 3

• b=1

• b=1/3

Randy charges his tenants $400 each month to rent his houses plus $600 security deposit. In the new year, the property taxes increased on the area where he rents so as a result he must increase the rate of change by $25 to ensure his profits are not harmed. What equation best represents how much his tenants will now have to pay? 

• y = 425x + 600
• y = 425 + 600x
• y = 400x + 625
• y = 400 + 625x
