Dinesh thinks that the point (1,3) is on the line y = 4x - 2.
State whether Dinesh is correct and give a reason to justify your answer.
pls help me thanks​

Respuesta :

To see if the point is on the line, plug in one of the point values to see if it equals out.

y = 4x - 2         I will plug in 1 for x to see if y does = 3

y = 4(1) - 2

y = 4 - 2

y = 2           so (1, 2)

Dinesh is not correct because the point on the line when x = 1 is (1, 2) not (1, 3)
