Translating

three units to the left can be done by choosing any coordinates on

.
Let choose (0,0) and (2,1)
Translating 3 units on to the left gives the new coordinates (0-3, 0)=(-3,0) and (2-3, 1)=(-1, 1)
The gradient of the two functions will stay the same since the lines are parallel to each other, so m = 0.5
By joining the two coordinates (-3,0) and (-1,1), we see that the translated line crosses y-axis at 1.5
The equation of translated line is given


The area of the irregular shape is the area of the two rectangles added together. Use the measure calculate feature of Geometer's Sketchpad to add the areas. The perimeter of the irregular shape is equal to the sum of the six segment around the outside of the figure.
