Answer:
(4, 2) becomes (-4, -2)
(4, 1) becomes (-4, -1)
(7, 1) becomes (-7, -1)
Explanation:
The directions say to reflect the shape over the line y=-x. so
Step 1: draw the line y=-x
Step 2: there are multiple ways to reflect a shape, but I feel like it'd be easiest to get a piece of graph paper, trace the grid, and fold/flip the graph paper over so you get the exact shape. Or you could count the units from shape a to y=-x, then double them, or since y=-x is a diagonal line, so you're going into the (-x, -y) quadrant, you could just invert the positive coordinates and turn them negative.
