BONUS: Write the equation of both lines given below, and then determine if the lines are parallel, perpendicular, or neither. Choose the correct
answer below.
Line 1: (1, 2) and (3, 1)
Line 2: (2.0) and (0, -1)
Line 1: y = 1/2 x + 2.5, Line 2: y = -2 x+1, Perpendicular
O y 1
Line 1: y = 2x + 1, Line 2: y = 2x - 1, Parallel
Line 1: y = -1/2 x + 3, Line 2: y = 2x-1, Perpendicular
Line 1: y = -1/2 x + 2.5, Line 2: y = 1/2 x - 1, Neither

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
