The intersection of the planes x+y+z = 1 and x+2y+2z = 1 is a line. Find two vectors p , q such that the solutions can be written in parametric form as.

Exercise 4: The intersection of the planes a + y + = = 1 and a + 2y + 2= = 1 is a line (This means that the system has infinitely many solutions). Find two vectors p, o such that the solutions can be written in parametric form as = p+ed
