The slope of this line is -1 you find this by using the slip formula of y-y over x-x find two points on the line so I used points (-2,2) and (-1,1) plug them into the formula to get the slope of -1 hope this helps:)

A circle whose center is the origin passes through the point (-5,12). Which point also lies on this circle?

schepotkina [342]

The answer is B(11, 2sqrt(12) )
proof

the main equation of the circle is (x-x1)²+(y-y1)²=R²
where C(x1, y1) is the center
so if the center is the origin, it is O(0,0), and the equation becomes
 (x)²+(y)²=R²
and the circle passes through the point (-5,2) so we can write
(-5)²+12²=R², it implies R= sqrt(25+144)=sqrt(169)=13

and for B(11, 2sqrt(12) ) 11²+ (2sqrt(12))²= 121 + 48= 169= 13
it is checked.
