PLEASE ANSWER THE TWO QUESTIONS IM BEGGIN YOU. What is the y - intercept?
(0,-2)
(0,-4)
(-2,0)
(4,0)

what is the equation of the line?

y = -2x - 4

y = -1/2x - 4

y = 1/2x

y = 2x - 2

y = 1/2x - 4

1: (0,-4)

2:-2x-4

Step-by-step explanation:

™The y-intercept refers to the value where the graph cuts the vertical line.

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.
