AP Calculus: Plot the points (2,1), (-3,5), and (7,-3) on a rectangular coordinate system.?
Plot the points (2,1), (-3,5), and (7,-3) on a rectangular coordinate system. Then change the sign of the x-coordinate of each point and plot the three new points on the same rectangular coordinate system. What conjecture can you make about the location of a point when the sign of the x-coordinate is changed? Repeat the exercise for the case in which the sign of the y-coordinate is changed.

You mirror the points along the axes.
change the sign of the x- coordinate and you mirror it along the y-axis. and vice versa.

to try this, you will positioned a "spoke" from the muse at perspective pi/4, or 40 5 tiers in case you like. Make it pass the two procedures, into the 1st and 0.33 quadrants. you will ought to pass back 3 units alongside the spoke into the 0.33 quadrant. The coordinates of the factor is r cos theta, r sine theta. for that reason, with theta = pi/4, cosine and sine are the two (sqrt 2) / 2. so which you're at (-3 sqrt 2 / 2, -3 sqrt 2 / 2) you may positioned those numbers into the calculator in case you decide on a decimal approzimation, regardless of the undeniable fact that this is extra valuable to pass away it purely like this, as this is seen the impressive type.
