Question

Does the point (4, 1) lie on the line y = 3x + 1 ?​

Answer 1

Answer:

no

Step-by-step explanation:

To determine if the point lies on the line, substitute x = 4 into the equation and if the value obtained equals the y- coordinate of the point then it lies on the line.

y = 3(4) + 1 = 12 + 1 = 13 ≠ 1

Thus (4, 1) does not lie on the line

Answer 2

Replace x in the equation with the x value of the point and solve for y. If Y equals the y value of the point then the point lies on the line.

y = 3x + 1

y =3(4) +1 = 12 +1 = 13

y = 13, this does not equal the y value of the point which is 1, so point (4,1) does not lie on the line.
