Question

I really need help with this my deadline is very soon​

Answer 1

`(3)\ y = -x`

`(5)\ y = -3x -2`

Explanation:

Required

The equation in slope intercept form

Solving (3):

`m = -1`

`(x_1,y_1) =(4,-4)`

The equation in slope intercept form is:

`y = m(x - x_1) + y_1`

This gives:

`y = -1(x - 4) -4`

Expand

`y = -x + 4 -4`

`y = -x`

Solving (5):

`m = -3`

`(x_1,y_1) = (1,-5)`

The equation in slope intercept form is:

`y = m(x - x_1) + y_1`

This gives:

`y = -3(x - 1) - 5`

Expand

`y = -3x + 3 - 5`

`y = -3x -2`
