1. Answer: [tex]\bold{\dfrac{188}{3}}[/tex]
Step-by-step explanation:
[tex]\dfrac{y_4-y_1}{x_4-x_1}=\dfrac{128-316}{4-1}=\large \boxed{-\dfrac{188}{3}}\\\\\\\text{The negative sign represents "decrease".}[/tex]

a) Shifted down 3 units
b) vertex = (0, -3)
c) Equation: y = | x | - 3
3. The parent graph is y = x²
a) Shifted right 1 and down 1 unit
b) vertex = (1, -1)
c) Equation: y = (x - 1)² - 1
