A VECTOR diagram uses arrows to show the size (#) and direction (positive or negative). Vectors pointing left are NEGATIVE Vectors pointing right are POSITIVE Vectors pointing left are Vectors pointing right are NEGATIVE ? POSITIVE ? positive The longer the positive vector, the more POSITIVE it is +1 positive more +2 positive +4 most The longer the positive vector, the more POSITIVE it is positive ? more positive ? most positive ? The longer the negative vector, the more NEGATIVE it is negative most -4 negative more -2 negative -1 most negative ? The longer the negative vector, the more NEGATIVE it is more negative ? negative ? What integer is shown by this vector? -4 -3 0 4 What integer is shown by this vector? -3 0 3 4 What integer is shown by this vector? You can show an expression on a vector diagram. The start point of the diagram will always be zero. Start at zero You can show an expression on a vector diagram.
