The straight line through two points will have an equation in the form \(y = mx + c\). We can find the value of \(m\), the gradient of the line, by forming a right-angled triangle using the ...

The linear regression equation is perhaps one of the most recognizable in statistics. It can be used to represent any straight line drawn on a plot: Where ŷ (read as “y-hat”) is the expected values of ...

The straight line through two points will have an equation in the form \(y = mx + c\). Then, we can find the value of \(c\), the \(y\)-intercept, by substituting the coordinates of one point into ...
