On the same coordinate plane mark all points (x,y) that satisfy the rule
y=-3x-x

There seem to be two mistakes in the given equation. First, there should be a coefficient of 3 on the x-term, which gives y = -3x - x = -4x. Second, the question asks for plotting the points that satisfy this equation, which would be a straight line, not isolated points. Therefore, the correct rule and graph are:
Rule: y = -4x

Note: The points on the line can be represented by any pair (x, y) that makes the equation true, such as (0, 0), (1, -4), (-2, 8), etc.
