Step-by-step explanation:
Part 1
Obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (1, 80) and (x₂, y₂ ) = (2, 110) ← 2 points from the table
m = = 30
Given the point (0, 50 ) ⇒ c = 50
D(g) = 30g + 50 ← linear equation
A
D(6.5) = (30 × 6.5) + 50 = 195 + 50 = 245
B
D(4.25) = (30 × 4.25) + 50 = 127.5 + 50 = 177.5
C
D(50) = (30 × 50) + 50 = 1500 + 50 = 1550
