Kyle is told that the distance between the lower waterfall and the upper waterfall in his favorite national park is about 1 and 1/2 miles. The distance between the falls on Kyle's map is about
1/2 inch. What is the unit rate calculated in miles per inch?

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.
