Answer:
y = -2x + 19
Step-by-step explanation:
Firstly, you need to do y = mx + b
Your y is going to be from the given y coordinate (3) , the m will be the slope (-2), and the x will be the from the given x coordinate (-8).
3 = -2(-8) + b Write out equation
3 = -16 + b Simplify
+16 = +16 + b Add 16 to both sides
__________
19 = b Now you have b
y = -2x + 19
-2x is your slope and +19 is your b
I think 12. I'm not sure though. The way I came up with that answer is the tree diagram. I used the numbers 1, 2, 3, 4, . Then I did the tree diagram method.
Answer:
14 hours and 42 minutes
Step-by-step explanation:
- 12 hours later is 7:18pm
- 2 hours later is 9:18pm
- 60-18=42 minutes
- 12 hours + 2 hours plus 42 minutes = 14 hours and 42 minutes
