Question

Does the point (3,7) lie on the line whose equation is y=3x-2

Answer 1

◆ check it !!

It this point lies on this line then it must satisfy it !

Given equation is y = 3x-2

LHS : y ans y = 7

Now RHS 3x- 2 = 3×3 -2 = 9-2 = 7

so LHS= RHS

so this point (3,7) lies on this line

Answer 2

`(3,7)\qquad\implies\qquad x=3\qquad y=7\\\\\\ y=3x-2\\\\7=3\cdot3-2\\\\7=9-2\\\\\boxed{7=7}\qquad\text{(true)}`

Answer is yes.
