Answer 1

my work

Answer 2

Use formula y = mx + b
substitue y = 4, x = -2 and m = -3

Answer 3

was i supposed to use the point-slope formula? or was i supposed to use y= mx+b ...

Answer 4

find b, then you have
4 = -3(-2)+b
4 = 6 + b
4-6 = b
-2 = b

Answer 5

oh ok

Answer 6

wait, after the thing i did? or do i erase it

Answer 7

Then you have the equation using formula
y = -3x -2
