The graphs represent the temperature of an oven over time. match each graph to its correct situation.
1. the oven door was opened once for a brief time during the cooking period.
2. the oven was initially heated to a higher temperature that needed for the cooking
3.the oven kept a somewhat constant temperature while cooking woth slight variations due to cooling and reheating.

Y= -2x-1 the negative in front of the 2 is because the slope is negative and the -1 is because it’s down 1 on the y axis.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
