Identify the graph of an equation

What you'll learn

  • Identify whether a given graph represents a linear equation by visually inspecting for a straight line with 80% accuracy.
  • Match a linear equation in slope-intercept form (y = mx + b) to its corresponding graph from a set of four options with 75% accuracy.
  • Explain how the slope (m) and y-intercept (b) in the equation y = mx + b affect the appearance of the graph in at least two complete sentences.
  • Determine if a graph represents a proportional relationship by verifying it is a straight line that passes through the origin (0,0) with 100% accuracy.
