A line passes through the points (7, 10) and (7, 20). Which statement is true about the line? V-yi
It has a slope of zero because X:-X, in the formula m=
is zero, and the numerator of a fraction cannot be zero.
It has a slope of zero because Xy - X, in the formula m=
is zero, and the denominator of a fraction cannot be zero.
y2-y1
o It has no slope because X2- *, in the formula m-
is zero, and the numerator of a fraction cannot be zero.
12-11
It has no slope because *,-X, in the formula m=
X-X
is zero, and the denominator of a fraction cannot be zero.

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.
