1.)if y = -5 when x=2, find y when x= 8 2.) If y = -7 when x = -21 what is the value of x when y= 9

These are two different questions obviously if you could answer both that would be great thanks!

Oh i'm sorry. didn't see the options

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.
