The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y - 4 =1/4(x-8). What is the slope - intercept form of the equation for this line?

Do one of the following, as appropriate: (a) find the critical value z subscript alpha divided by 2 , (b) find the critical value t subscript alpha divided by 2 . 99%; nequals 17; sigma is unknown; population appears to be normally distributed.

Who ever answers this will get a cookie from batman

100 points and 1- -12=y-36 2- x/25=-25 3- -n=40
