Question

The points (0,1) (2,7) (-2,-7) (-1,-4) all fall on the line y = 3x + 1

• A. True
• B. False

Answer 1

The correct option is B

False

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

$⟹1=\left(3x0\right)+1$

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

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

$⟹7=(3\times 2)+1$

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

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

$⟹-7\ne (3\times (-2\left)\right)+1$

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

Putting x = -1, y = -4 in y = 3x + 1

$⟹-4\ne (3\times (-1\left)\right)+1$

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