The equation y=2.54x is used to convert inches into centimeters. The "x" in the equation represents the number of inches you are trying to convert into centimeters. The "y" in the equation represents the the number of centimeters that the inches are converted into.
This graph has a positive slope of 2.54 and has a y intercept of 0. Each point on this graph represents how many centimeters are in each inch.
In order to find the number of centimeters you would out 12 inches into the equation. Therefore, the equation would look like y=2.54(12). So then y=30.48 centimeters.
