Plotting linear equations:

  • Straight lines not through the origin, any gradient
  • Straight lines not through the origin, integer gradients
  • Straight lines through the origin, any gradient
  • Straight lines through the origin, integer gradients

HOW TO PLAY

Use your skills to plot a linear graph that matches the line to destroy space debris. Change the gradient and y-intercept to correctly position the missile, before firing towards the space debris.

  1. Click on the gradient in the equation, and change it using the dial.
  2. Click on the y-intercept, and move the slider up or down to change the value
  3. Once you're happy with the positioning of the line, click FIRE

You have two attempts the answer the question. After this, it is auto-corrected, and another question is revealed.

SCORING INFORMATION

For each level, reach the in-game goal and beat the target score to earn a medal (Bronze, Silver, Gold)

  • In-game goal: Answer 1 Medium question in the first attempt >>> Target score >>> 135-294 points (B)
  • In-game goal: Answer 1 Hard question in the first attempt >>> Target score >>> 295-509 points (S)
  • In-game goal: Answer 3 Hard questions in the first attempt >>> Target score >>> 1800+ points (G)

Scoring calculation

The score is calculated as follows:

BASE SCORE: Players have 2 attempts to answer a question, otherwise it is auto-corrected. Players gain double the amount of points for answering the question correctly on the first attempt compared to their second.

  • Answered correctly in first attempt - 10 points
  • Answered correctly in second attempt - 5 points
  • Incorrect (auto-corrected) - 0 point

DIFFICULTY: There are 3 difficulties per level.

  • Players start on easy and move up to medium then hard.
  • Correctly answer 2 questions in a row on your first attempt to go up a difficulty
  • Get 2 incorrect in a row to go down

BONUSES: There are 2 different bonuses that can be obtained in the game, Speedy bonus and Medal bonus.

  • Speedy bonus: 3 extra points for answering the question within 20 seconds
  • Medal bonus:
