x + y = 4 (2)

rearrange (2) to y = 4 - x (could do x = 4 - y )

substitute y = 4 - x into (1)

hence:

factor and solve : 2x(x - 4 ) = 0  

⇒

,

x

=

4

substitute these values into y = 4 - x , to find corresponding values of y.

x = 0 : y = 4 - 0 = 4 → (0 , 4)

x = 4 : y = 4 - 4 = 0 → (4 , 0 )

These are the points of intersection with the line x +y = 4 and the circle
