Hey there!
Let's take a look at this problem... Okay so for these questions there is formula known as the point-slope formula that is used...
(y - y₁) = m(x - x₁)
From here on out you substitute in your given values...
(y + 3) = -6(x + 2)
y + 3 = -6x -12
y = -6x -15 <----- That's your answer!
I hope this helped you!
