To reflect a shape across a vertical line, such as line ( x = x_1 ), you first determine the horizontal distance from each point of the shape to the line. For a point ( (x, y) ), the reflected point will have coordinates ( (2x_1 - x, y) ). This process is repeated for all points of the shape to obtain the reflected image. The resulting shape will be a mirror image of the original across the specified line.

How do you find the perimeter to a shape on a grid?
To find the perimeter of any shape, simply add the lengths of the individual line segments together. To find the length of an individual line segment (x1,y1)-(x2,y2) simply compute the square root of (x1-x2)2 + (y1-y2)2.
What is the slope formula in equation form?
If (x1, y1) and (x2, y2) are two points on the line, then the formula for the slope is (y2-y1)/(x2-x1) provided x2 ≠x1. If x2 = x1 then the line is vertical and the slope is not defined.
