5. science a spring stretches in relation
to the weight hanging from it according
to the equation y 0.75 +0.25 where
is the weight in pounds and y is the
length of the spring in inches.
2. graph the equation include axis labels
interpret the slope and the
tercept of the line.
how long will the spring beifa 2-pound weight is hung on it? will the
length double if you double the weight? explain

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.

step-by-step explanation:

the answer would be 44.79
