Question

(4.9) and (2, -6)
I need to write it in standard form

Answer 1

Explanation:

`Slope=(y_(2)-y_(1))/(x_(2)-x_(1))\\\\=(-6-9)/(2-4)=(-15)/(-2)=(15)/(2)\\\\`

Equation:

`y -y_(1)=m(x -x{1})\\\\y - 9 = (15)/(2)(x-4)\\Multiply \ the \ entire \ equation \ by 2\\\\2*(y -9)=2*(15)/(2)(x-4)`

2y - 2*9 = 15(x - 4)

2y - 18 = 15x - 60

2y - 18 + 60 = 15x

2y + 42 = 15x

15x - 2y = 42
