Choose the equation that represents the given graph
a. y=3sin (1/2x)
b. y=2sin(1/3x)
c. y=3sin(2x)
d. y=2sin(3x)

Aperpendicular bisector, cd is drawn through point con ab if the coordinates of point a are (-3, 2) and the coordinates of point b are (7,6), the x-intercept of cd is point lies on cd.

Solve the given system of equations. 2y= -x+9 , 3x-6= -15

Select the conic section that represents the equation. 3x2 + 3y2 -2x + 4 = 0
