In the standard (x,y) coordinate plane, an equation of a circle is x² + y² = 64. At what points does the circle intersect the yaxis?
A.) (0,1) and (0,1) B.) (0,8) and (0,8) C.) (0,9) and (0,9) D.) (0,10) and (0,10) E.) the circle does not intersect the yaxis
When a graph intersects the yaxis, the value of x is equal to zero.
To find the yintercepts, set x equal to zero. x² + y² = 64 0² + y² = 64 {substituted 0 for x} y² = 64 {simplified} y = 8 or 8 {took square root of each side} The coordinates of the yintercepts would be B.) (0,8) and (0,8) Comments are closed.
