Answer/Step-by-step explanation:
1. 5x + y = -10
5x + y = -10
-5x -5x
------------------------
y = -5x - 10
m = -5 or (-5/1)
b = -10 or (0, -10)
Point 1: (0, -10)
Point 2: (1, -15)
Point 3: (2, -20)
----------------------------------------------------------------------------------------------------------
2. 2x + 2y + 4 = 0
2x + 2y + 4 = 0
-4 -4
---------------------------
2x + 2y = -4
-2x -2x
-------------------------
2y = -2x - 4
÷2 ÷2 ÷2
-------------------
y = -1x - 2
m = -1 or (-1/1)
b = -2 or (0, -2)
Point 1: (0, -2)
Point 2: (1, -3)
Point 3: (2, -4)
I hope this helps!
