Understanding how to calculate the y-intercept is a fundamental concept in algebra, helping students analytically understand linear functions and graphing. The y-intercept represents the point at ...

Any straight line graph has a constant gradient, which is calculated by the change in 𝑦 divided by the change in 𝑥, along any section of the graph. The gradient is measuring the steepness of the ...

R², also known as the coefficient of determination, is a statistical measure used to ascertain the strength of the relationship between dependent and independent variables. It is particularly useful ...

The y-intercept is the point at which a linear equation crosses the y-axis on the x=0 plot point. The equation to determine both the slope and the y-intercept of a line is y=mx+b. This calculation may ...
