1.25x
because 25% can be represented as 0.25. so as the new price would be 125% of the old one its 1.25x
I'd say an outlier. P is separated noticably from the other points and would not considerably affect the slope of the line
T: 8x+19
7x-2(4-2x)+6(5-x)-x+2-(6x+5) = 7x-8+2x+30+6x-x+2-6x-5 = 8x+19
Y: 56-8x
9-(-2-3x)+4(-x+6)-x+12-3(2x-3) = 9+2+3x-4x+24-x+12-6x+9 = 56-8x
The answer is D because there is one of the 0 and one of the 9
