Writing Equations in Slope-Intercept Form: Sample FAST Questions

Writing y = mx + b from a graph, a table, or a word description is the 8th grade skill that ties slope and intercept together. Students find the rate of change, find the starting value, and assemble the equation.

How the FAST tests this benchmark

FAST items include equation editor questions where students type the whole equation, multiple choice items, and drop-down items that ask for the slope and the intercept separately. Reading a y-intercept off a table means finding the value at x = 0, which is often not the first row shown.

Skills students need

  • Write a slope-intercept equation from a graph
  • Write a slope-intercept equation from a table
  • Write a slope-intercept equation from a written description
  • Identify slope and y-intercept from an equation
