Answer: Point-Slope
Step-by-step explanation:
Point-Slope: y - y₁ = m(x - x₁) ; where m is the slope and (x₁ , y₁) is the point
Slope-Intercept: y = mx + b ; where m is the slope and b is the y-intercept
************************************************************************************************
y - 2 = -3(x - 1) is in Point-Slope form where -3 is the slope and (1, 2) is the point
