Question

Question 6 Which of the following points lie on the line whose equation is y - 4 = (x + 2)? 2 0 (-7, -1) O (8, 11) 0 (3, 7) O (1, 5) 0 (-1,0)

Answer 1

Given:

y - 4 = (x + 2)

Put the equation in respect of y:

y = x + 2 + 4

y = x + 6

To find the points, let's solve for each of the given options:

a) For (-7, -1). When x is -7, y is -1

Here substitute x for -7 and y for -1:

-1 = -7 + 6

-1 =-1

Correct

B) (8, 11)

substitute x for 8 qnd y for 11

y = x + 6

11 = 8 + 6

11 = 14

Wrong

c) (3, 7)

Substitute x for 3 and y for 7

y = x + 6

7 = 3 + 6

7 = 9

Wrong

d) (1, 5)

Here substitute x for 1 and y for 5:

y = x + 6

5 = 1 + 6

5 = 7

Wrong

e) (-1, 0)

Here substitute x for -1 and y for 0:

y = x+ 6

0 = -1 + 6

0 = -5

Wrong

We can see the only option that equates to y is choice A.

ANSWER:

(-7, -1)
