Step-by-step explanation:
Car A drives 1280 miles in 16 hours.
Speed =
The speed rate of car A = = 80 miles per hour
Car A travels 0.5 miles per hour faster than car B.
∴ Speed of car B = 80 - 0.5 = 79.5 miles per hour

Step-by-step explanation:
Use the change-of-base rule.
slope = -
calculate the slope m using the gradient formula
m= (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (- 3, 6)
m = =
= -
