Answer:
A system of the equation of a circle and a linear equation
A system of the equation of a parabola and a linear equation
Step-by-step explanation:
Let us verify our answer
A system of the equation of a circle and a linear equation
Let an equation of a circle as
..........(1)
Let a liner equation Y = x ............(2)
substitute (2) in (1)

so Y =
so the two solution are (
)
A system of the equation of a parabola and a linear equation
Let equation of Parabola be 
and linear equation y = x
substitute

Y = 0,1
so the two solutions will be (0,0) and (1,1)
