Answer:
Part A: (3, 2)
Part B: 5
Explanation:
Point B of the parallelogram is the top right dot on the graph. In order to find its coordinate, we simply trace the dot's trajectory back to the x and y axis accordingly. If we look under the dot we see that its x-axis is 3 and if we look to the left of the dot we see that its y-axis is 2. Therefore, the coordinate of the fourth vertex B is (3, 2)
To calculate the length of side AB we simply count the number of squares between them, which looking at the graph we can see is 5 squares. Therefore the length of AB is 5
