Solution

The correct option is B

False


Putting x = 0, y = 1 in y = 3x + 1 =>

1=3×0+1

Equation is satisfied. Hence, (0, 1) is on the line.

Putting x = 2, y = 7 in y = 3x + 1 =>
7=3×2+1

The equation is satisfied. Hence, (2, 7) is on the line.

Putting x = -2, y = -7 in y = 3x + 1 =>

73×2+1

Equation is not satisfied. Hence, (-2, -7) is not on the line.

Putting x = -1, y = -4 in y = 3x + 1 =>
43×1+1

The equation is not satisfied. Hence, (-1, -4) is not on the line.
