Answer 2

Answer:

(iv) ( 4 , 12 ) does not lie on line y = 3x + 4

Step-by-step explanation:

Given equation,

$y = 3x + 4$

also given,

(i) ( 1 , 7 )

(ii) ( 2 , 10 )

(iii) ( -1 , 1 )

(iv) ( 4 , 12 )

Now, substituting (i) in given equation

$7 = 3(1) + 4 \\ 7 = 7$

LHS = RHS

Now, substituting (ii) in given equation

$10 = 3(2) + 4 \\ 10 = 6 + 4 \\ 10 = 10$

LHS = RHS

Now, substituting (iii) in given equation

$1 = 3( - 1) + 4 \\ = - 3 + 4 \\ 1 = 1$

LHS = RHS

Now, substituting (iv) in given equation

$12 = 3(4) + 4 \\ 12 = 12 + 4 \\ 12 < 16$

LHS is not equal to RHS

Hope this answer helps you.
