The slope of any line passing through (0, 0) can be seen as

*. Any part/whole fraction can be represented as a slope ratio with the numerator =***y**/**x***and the denominator =***y***. Use the slider on the***x***-axis to determine the whole, and the slider on the***x***-axis to represent the part in a fraction (i.e.,***y***). Similarly, a ratio of***y**/**x***:***a***can be represented as***b***using the slider on the***a**/**b***-axis for***y***and the slider on the***a***-axis for***x***. The ratio of***b***is proportional to the percent value (i.e.,***y**/**x***/100). So, for example, a ratio of 10/40 can be seen as equivalent to 25/100, which is 25%. The ratio of the unit rate (i.e.,***p***1) is also proportional to any ratio expressed as***r**/*. So, a ratio of 10/40 has a unit rate of 1/4 : 1, or 0.25.***y**/**x**
