When you graph a series of (x,y) coordinates in Microsoft Excel 2010, you can use the program's built-in functions to display the equation for the line created by those data points. This allows you to ...

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 ...

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 ...

The graphs of \(y = 2x + 1\) and \(y = 2x - 2\) are shown below. The graph of \(y = 2x + 1\) crosses the \(y\)-axis at (0, 1). The graph of \(y = 2x - 2\) crosses the ...

with B * = I- B. This requires that one of the preceding equations be solved for P t. Solving the second equation for P t yields You can estimate the intercepts of a system of simultaneous equations ...
