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 ...

Before calculating ... along the line from left to right, you would be walking downhill, so the gradient will be negative. Then, choosing two random points on the line and using the same method ...

I’m sure most of us have experience in drawing lines of best fit, where we line ... at this point that this method is intended for continuous data. But we’re getting ahead of ourselves. To calculate b ...

What’s in an equation? Letters and numbers and odd symbols ... This arose in part from the problem of trying to calculate the slope of a curved line at any given point. It’s a question that ...

Estimating the regression equation by LSE is quite robust to non-normality of and correlation in the errors, but it is sensitive to extreme values of both predictor and predicted. Linear ...

Before students are presented with the quadratic formula, they’re taught a simpler method to solve certain equations. For simplicity, we’ll consider an equation where a = 1. Figuring out the ...
