Question

A line is given by the equation y=x+2. Determine which of the following points belong to this line: M(0, 2),N(1, 3), A(−1, 1), B(−4.7, −2.7), C(−2 1 2 , 1 2 ).

Answer 1

A(-1, 1)

Explanation:

Answer 2

M,N,A,B

Explanation:

all the points above satisfy the given eqn

eg, A(-1,1)

y=x+2,x=-1

y=-1+2

y=1 but C doesn't satisfy the eqn (-2 1/2,1/2)

y= -2 1/2 +2

y= -1/2
