Acircle has center o(−3, 1) and radius 10. which of the following points is on the circle? a. v(−3, −4) b. x(5, −2) c. y(−6, 0) d. z(5, 7)

Try this solution:
1. common equation of circle is (x-a)²+(y-b)²=r², where a,b - coordinates of the centre, r - radius of the circle.
2. using point O and radius: (x+3)²+(y-1)²=100 - the equation of the circle.
3. substituting point V,X,Y and Z into the equation of the circle:
V: (-3+3)²+(-4-1)²=100 - false;
X: (5+3)²+(-2-1)²=100- false;
Y: (-6-3)²+(0-1)²=100 - false;
Z: (5+3)²+(7-1)²=100 - true.

Just divide the x axis (the top) by 2 or multiply the y axis (the bottom) by 2

Just a question- could you organize the data better? i just cannot tell which number are for which bakery. i will be happy to answer this question if you could do this for me! : )
