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 ...
You will learn how to graph each equation on the same set of axes, using their slope and y-intercept to plot the lines accurately. Step-by-step examples demonstrate how to determine the point of ...
So let's look at first what slope-intercept form is. Slope intercept form is actually y equals mx plus b. The reason why it is called slope intercept form is because it gives a slope and an intercept.
Plot points with coordinates where \(x\) and \(y\) are equal. Three points are sufficient, but more can be plotted. Draw a line through the plotted points. If \(x\) is positive, \(y\) is negative. If ...
Any equation that can be rearranged into the form \(y = mx + c\), will have a straight line graph. \(m\) is the gradient, or steepness of the graph, and \(c\) is the \(y\)-intercept, or where the line ...
