Graph a set of coordinates in Excel 2010, display the equation and solve the equation using the value "0" for x to determine its y-intercept.

Any equation that can be rearranged into the form y = m x + 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 crosses ...
