How do you rotate 90 degrees counterclockwise about the origin?

Mathematics

When rotating 90 degrees counterclockwise about the origin, the original coordinates are changed according to the rule (-y, x). Therefore, we take the original coordinates and switch them up accordingly to the rule listed above. When we do so, we get the coordinates Z'(4,0); J'(2,-5); L'(3,0). Hope this helps and have a phenomenal day!

What is the equation of this circle in standard form M(2,4) N(9,4) these are coordinates across the diameter of the circle?
igomit [66]
The standard form is

(x-xo)² + (y-yo)² = r²

Where xo,yo is the center of the circumference
and r is the radius.

We find the distance between the points to determine the <span>diameter

d=sqrt ((9-2)</span>² + (4-4)²<span>) = sqrt (49) = 7

The radius of the circumference is d/2 = 7/2 = 3.5

And we can see that those points are at the same coordinate y = 4 

The center is given then by , x = (9+2)/2 = 5.5
                                              y = (4+4)/2 = 4

The equation results

(x-5.5)</span>² + (y-4)² = (3.5)²<span>

Solve by inspection: X+4=15
amid [387]

x + 4 = 15

- 4        -4

x = 11

You would subtract 4 because you need to isolate the x to get the value of x. You would subtract it to both sides because whatever you do on one side, you have to do it to the other side.
