What does Y MX C mean?
y = mx + c is an important real-life equation. The gradient, m, represents rate of change (eg, cost per concert ticket) and the y-intercept, c, represents a starting value (eg, an admin. fee).
Do all conversion graphs start at 0 0?
Data in a line chart is encoded by position (x, y coordinates), whereas in a bar chart data is represented by length. This subtle difference changes the way a reader uses the chart, meaning that in a line chart it’s ok to start the axis at a value other than zero, despite many claims that they are always misleading.
