Question

Which of the following points lies on the line y = x + 1? (a) (2, 1) (b) (1, 2) (c) (3, 2) (d) (0, 0)

Answer 1

Answer:

only point b) (1, 2) lies in the given line

Step-by-step explanation:

given, line is y = x + 1.

so, any point that lies on this line must satisfy the equation.

a) (2,1)

putting x =2 and y = 1 in y = x +1 does not satisfy the equation. So the point a) does not lie in the given line.

similiarly c)(3, 2) and d)(0,0) doesnt satisfy the equation y = x +1.

but in case of point b) (1, 2)

putting x = 1 and y=2 in eq x = y +1 we get,

2 = 1 +1 => 2 = 2. which is True

ie, point b)(1, 2) satisfies the equation of given line.

so point b) (1,2) lies on the line y = x +1.
