Please excuse my lack of understanding Windows 7 and Excell.
I have included a sketch of a graph; y = 2x + 2
I have sketched this on graph paper and the appearance is the same as the attachment. I am happy that I have sketched the graph correctly, however I can't get Excell to re-produce the same graph?
It's quite clear that when inputting the data, i.e. when x = 0 y = 2 and the coordinates (3,8) and (-5, -8) that I am clearly getting it wrong, the graph is like a uneven land scape?
I know the graph is a straight line graph which cuts the y axis at 2, but I can't get Excell to do it?
Would someboby please show me how to input the data correctly.
