For this case, we have the following expression:
We simplify the expression:
If we add similar terms, taking into account that different signs are subtracted and the sign of the greater one is placed, we have that
So, we have to:
Answer:
-3x + x + 5 = -2x + 5
Answer:
zero
Step-by-step explanation:
The optimally fitted straight line via the locations and points on a graph is determined via linear regression. You may use regression equations to see if your data can indeed be fitted into a formula. If you want to create assumptions from your data, either future forecasts or indicators of previous behavior, using the Regression equation is highly beneficial.
The regression line is expressed as:
where;
= dependent variable
a = intercept
b = slope
= independent variable
So, when is independent of the variation of
, it means that
does not linearly depend on
. Thus, the slope of the regression will be zero.
