The independent variable x from a linear regression is measured in miles. If you convert it to kilometres (keeping the unit of the dependent variable y the same), how will the slope coefficient change? (note: 1 mile = 1.6 km)

Answer:
If you convert it to kilometres (keeping the unit of the dependent variable Y the same), how will the slope coefficient change (1 mile = 1.6 km)? ... However, a change to all of the values of x to make them in kilometers will result in a change of the slope coefficient used to compute y relative to a new set of x values.

Answer:
In the linear regression equation, X gets multiplied by 1.6 with no change in Y. So, the slope will be divided by 1.6.
