In math and statistics, you may occasionally need to calculate the slope of a line generated by coordinates in the (x,y) format. The slope is a value that indicates the rate at which the y value of a ...

Calculating the slope of a line on a graph is a fundamental skill in algebra, geometry, and calculus. The slope indicates the steepness of the line and can also show the relationship between two ...

The concept of slope is important in economics because it is used to measure the rate at which changes are taking place. Economists often look at how things change and about how one item changes in ...

A derivative is a function which measures the slope. It depends upon x in some way, and is found by differentiating a function of the form y = f (x). When x is substituted into the derivative, the ...

Microsoft's Excel software for Mac can execute a number of statistical functions, including finding the y-intercept of the line formed by a set of data points. Excel's intercept function takes the ...

The graphs above, \(y = 2x + 1\) and \(y = 2x - 2\) have the same gradient of 2. The lines are parallel. State the equation of a line that is parallel to \(y = 3x + 7\). To be parallel, two lines must ...
