In the least squares = ,
a) what is the value of the slope?
b) When increases 1 unit, by how much does change?
Let x be independent variable and y be dependent variable.
Least square Regression equation is
= a + b *x
where a is intercept and b is slope and is predicted value of y for some x.
The slope is rate of change when x increases by 1 unit then the changes by b units.If slope is positive then the increases and if slope is negative then decreases.
