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.

How to Find the Slope of a Line on an Excel Graph. In math and statistics, you may occasionally need to calculate the slope of a line generated by coordinates in the (x,y) format.

Excel's intercept function takes the data points that define a line on a graph and calculates the y value for the point on the graph where x is equal to zero.

The top part of that image is the equation itself. The bottom part is a graph of the equation, which, as you can see, is exactly the same. To be fair, this equation cheats a little bit.

In fact, this is how you begin the procedure for finding rational points on elliptic curves: Find a single rational point, then find the equation of the tangent line and see where it intersects the ...

The second option allows you to customize how an equation is depicted on the graph. In cases where you want to compare two equations, you might want one to them to be a striped or dotted line/curve.

You can make a line graph in Excel in a matter of seconds using data already entered into the spreadsheet.
