Question

4. Which of the following points does not lie on the line y = 2x +4?
(a)(1,7)
(b) (2,10)
(c) (-1,1)
(d) (4, 12)​

Answer 1

a. y=2*1+4

y=6

but y=7

so it doesn't lie on line

b. y=2*2+4

y=8

so it also not lie on line

c. y=2*-1+4

y=2

so it also not lie on line

d. y=2*4+4

y=12

so it lies on line

so a,b,c are the desired answer

mark as brainlist..

thank you

Answer 2

Answer:

(a.), (b.) and (c.)

Step-by-step explanation:

We will check by plugging all these points into the equation

(a.)

7 = 2(1) + 4

7 not = 6

This is not on the line

(b.)

10 = 2(2) + 4

10 = 4+4

10 not = 8

This is not on the line

(c.)

1 = 2(-1) + 4

1 not = 2

This is not on the line

(d.)

12 = 2(4) + 4

12 = 8 + 4

12 = 12

This is on the line
