A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation. STEP 1 - Draw a ...

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 ...

By identifying two points on a line, applying the slope formula, and correctly interpreting its meaning, you can effectively determine relationships between variables and understand trends in data.

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 ...

In this case both the slope and the y intercept are known and the equation can be written directly. For example if the slope is -2 and the y intercept is (0,6), then the equation is In this case the ...

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 ...

1. Find the equation of the line which passes through the points (5,1) and has a slope of .5. In this case the slope and one set of coordinates are known. This case involves the use of the point-slope ...

Everything in physics is described by an equation. Equations can describe the shape of lines, curves, surfaces, and just about any object you can think of. In fact, you’d be hard-pressed to think of ...

Our teacher already knows there is a positive relationship between how much time was spent on an essay and the grade the essay gets, but we’re going to need some data to demonstrate this properly.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
