Patterns, Functions, and Algebra

Virginia SOL 8.PFA.3

Represent and solve problems using linear functions and analyze their key characteristics.

What students need to be able to do

  • Determine how adding a constant (b) to the equation of a proportional relationship y = mx will translate the line on a graph.
  • Describe key characteristics of linear functions including slope (m), y-intercept (b), and independent and dependent variables.
  • Graph a linear function given a table, equation, or a situation in context.
  • Create a table of values for a linear function given a graph, equation in the form of y = mx + b, or context.
  • Write an equation of a linear function in the form y = mx + b given a graph, table, or a situation in context.
  • Create a context for a linear function given a graph, table, or equation in the form y = mx + b.
