Answer:
The slope of the linear equation will be 60 and the point on the line will be (6,1250).
R - 1250 = 60(y - 6)
Step-by-step explanation:
An apartment lease states that the rent will go up by $60 each year. The rent in the 6th year is $1250.
Therefore, the slope of the linear equation will be 60 and the point on the line will be (6,1250).
Now, the point-slope form of the linear equation which models the rent (R(y)) in terms of how many years (y) the tenants have lived there will be 
R - 1250 = 60(y - 6) (Answer)
