It will take 20 months for the cost to be same.
Step-by-step explanation:
Apartment A;
Security deposit = $1000
Each month cost = $1200
Let,
x be the number of months.
A(x) = 1000 + 1200x
Apartment B;
Security deposit = $1500
Each month cost = $1175
B(x) = 1500 + 1175x
The cost will be same when the functions are equal, therefore,
A(x) = B(x)

Dividing both sides by 25

It will take 20 months for the cost to be same.

Answer:
Y=-4x
Step-by-step explanation:
We know the slope is negative since the line decreases from left to right. Starting at 0,0 we go down 4 and to the right 1 to get to the next point. Therefore the slope is the change in y over the change in x or -4/1= -4. The y intercept is 0 since it crosses the y axis at 0,0. The equation of the line in slope intercept form is y= mx+b or y= -4x
