The graph of y =8x goes through the origin (0,0) the graph of Y = 8x-1 is displaced on the negative y -axis and goes through the point (0, -1)
Right-angled triangle. Let x be the required angle. Tan x = 8/6. x= 53.1°
Y=(x+1)(x-1) this is factored out
$58.08 I think that’s what I got when I typed it in the calculator
The mean increases when the outlier is removed
