Math

Definition

Writing from graphs involves interpreting visual data displays and translating the information into equations, inequalities, or written descriptions. This skill requires reading coordinates, identifying slopes, recognizing function types, and understanding the relationship shown in the graph.

Examples

  • Reading two points from a line graph to write y = mx + b
  • Identifying the vertex of a parabola on a graph and writing the equation in vertex form
  • Describing a trend from a scatter plot as 'As temperature increases, ice cream sales increase'
