Yes, your graph would look slightly different if you had started with 10 bacteria instead of 1 since this is shown by the y-intercept. If you look at the graph you had drawn, the y-intercept of the graph is at the value (0,1). This shows the starting point of the bacteria. However, if you started at 10, then your line would move up to the point (0,10) meaning instead of it crossing (0,1) on the y-axis, it would cross the point (0,10) which is it's starting point if you start at 10 bacteria.
The graph would look different, because the starting point would be different. Since here you started at 0, because there were 0 bacteria in the beginning, it would instead start higher up. The slope would also be greater, since you're starting with 10 * 2, and then continuing to multiply from there, instead of with powers of 2.
