that has the same x & z intercepts as the plane with equation 2x + 5y - z + 7 = 0. In vector form.
One of the points is (0, 0, 7), another is (-7/2, 0, 0), and using those I can get the vector [7/2, 0, 7].
However, the answer is given with a vector of [1, 0, 2]. Where did this vector come from?

One of the points is A(0, 0, 7), YES correct
another is B(-7/2, 0, 0), YES also correct
line L= OB - OA = [-7/2, 0, -7] ~ [-7, 0 , -14] ~ [7, 0, 14] ~ [1, 0, 2]
as k[x,y,z] for line is same line for any non-trivial 'k'
Any examiner will know this in your answers so dont worry.
