What's on the worksheet

  1. Start at the y-intercept, step by the slope, and find the point you reach:
    y = 3x + 1; 4 steps to the righty = \dfrac{2}{3}x - 1; 3 steps to the righty = -\dfrac{5}{2}x + 4; 2 steps to the lefty = -0.6x + 2; 2 steps to the righty = \dfrac{7}{4}x; 3 steps to the left
  2. Write equations for the four sides of a rectangle and give their slopes.
  3. Find the intercepts of a line from its equation and graph it by stepping.
  4. Mei repeats a step of 3 left and 2 down: find the point and write the line's equation.
  5. Check Noah's rewritten equation and the plotted points on his graph.
  6. Explain why a fractional y-intercept is a poor place to start stepping, and find a better point.
  7. Word problem: the height of a submarine rising from 72 meters below the surface.
