Wanda has $640 in her checking account. she pays her landlord $75 per week for rent.

which function best models the linear relationship?

y = 640x + 75
y = −75x + 640
y = −75x - 640
y = 75x + 640

y = 75x + 640

Step-by-step explanation:

y = Mx + B

B= 640      M= 75    x= x

So,  

y = 75x + 640
