Answer:
Step-by-step explanation:
3y+7=2x
3y=2x-7
y=(2/3)x-7/3
when parallel, the y=ax+b, the a keeps the same
so it‘s y=(2/3)x-a
and it pass (2,6), so 6=(2/3)*2 -a
6=4/3-a
-a=(18-4)/3
-a=14/3
a=-14/3
The temperature at 5 am was -3 degrees
12-15=-3
slope=<u>y</u><u>2</u><u> </u><u>-</u><u> </u><u>y</u><u>1</u>
x2 - x1
= <u>-</u><u>1</u><u> </u><u>-</u><u> </u><u>-</u><u>3</u>
-7 - -9
= <u>-</u><u>2</u>
-2
= 1
I think the answer is D
