Which equation models this relationship in point-slope form using the point (1,−1)(1,-1) ? A. y−1=3(x+1)y-1=3(x+1) B. y+1=3(x−1)y+1=3(x-1) C. y−1=−3(x+1)y-1=-3(x+1) D. y+1=−3(x−1)y+1=-3(x-1) Review Progress Question 22 of 30

Studdy Solution
The equation that models the relationship is y+1=−3(x−1)y + 1 = -3(x - 1), which corresponds to option B.
