# Create scatter plot using base R
plot(x = mtcars$hp, 
     y = mtcars$mpg,
     xlab = "Horsepower (hp)", 
     ylab = "Miles Per Gallon (mpg)",
     main = "MPG vs. Horsepower: Vehicle Efficiency Analysis",
     pch = 19,  # Solid circles
     col = "blue")

Interpretation

There is a slight negative relationship between mpg and hp
