Mental Math Using the slope formula, find the slope of the line through the points (0.0) and (3.12). Use pencil and paper. Explain how you can use mental math to find the slope of the line.

Don’t worry about it

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.
