Graphing Linear Equations with Robots 2: Slope & y-intercept
Problem Statement:

Given y = -2/3x + 6. Have the tickbot graph the line described by this equation by plotting a point and using the slope to find additional points. Your graph must go through the y-intercept and contain three additional points not including the y-intercept. The points should lie on both sides of the y-intercept (in Quadrant II and I). Have the last point of the line be (6,2).
