Lin, and illustrator, pays $40 for each art class she attends. The equation y=40x represents the relationship between the number of classes and the amount Lin spends. She has $550 to spend. How many art classes can Lin pay for? X represents? ————-
Y represents? ————-

K=—————

Solution(———,———-)

The solution does or does not make sense in this situation because ————

Lin can pay ———- art classes

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
