Addition and subtraction - balance equations - up to 20

What you'll learn

  • Calculate the value of a missing coordinate on a line when given the slope and another point on the line with 80% accuracy on a quiz.
  • Solve for a missing x or y coordinate using the slope formula and given information in at least 3 out of 4 word problems.
  • Explain how the slope formula (m = (y2 - y1) / (x2 - x1)) can be used to determine a missing coordinate, providing a clear justification in writing.
  • Identify when it is possible to use the slope formula to find a missing coordinate given two points and the slope, and when it is not, providing a justification based on the information provided.
