I have to go in like 2 minutes, so I won't be able to explain it in full detail, but I hope this helps. Have an amazing day :)
-4x + y = 6
-5x - y = 21
add both of them
-9x = 27
x = -3
(-4*-3) + y = 6
-12 + y = 6
y = 18
Answer:
20
Step-by-step explanation:
Use the distance formula:

The slope is -3/2
Use the two ordered pairs (-2,0) and (0,-3) and do y2-y1/x2-x1
-3-0/0+2= -3/2
