Which is an equation in point-slope form for the line that passes through the points (-1,4) and (3,-4)? a) y+4=-2(x-3)
b) y-3 = -2(x+4)
c) y-4=2(x+3)
d) y+4=2(x-3)

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.
