Question

Can someone help with questions 3,4 and 5? THANK YOUUU ^^ I did questions 1 and 2

Answer 1

Question 3.

`y = (2)/(7) x - 3`

question 4

`y = - 4x - 1`

question 5

`y = 5x + 3`

Explanation:

Question 3

1.Write down what is given in equation form

`y = (2)/(7) x + c`

2. Insert the given point to work out c

`- 5 = (2)/(7) ( - 7) + c`

`c = - 3`

3. answer

`y = (2)/(7) x - 3`

Question 4

1 write what was given in an equation

`y = - 4x + c`

2. insert given point (-1;3) to work out c

`3 = - 4( - 1) + c`

`c = - 1`

3. final answer

`y = - 4x - 1`

question 5

1.with what was given write it in equation form

`y = 5x + c`

2. substitute the given point (-2;-7) to work out c

`- 7 = 5( - 2) + c`

`c = 3`

3.final answer

`y = 5x + 3`
