Label the slope and y intercept

slope= -4/3, Y-intercept: 7

Step-by-step explanation:

So for the slope, you use y2-y1/ x2-x1:

-1 - 3/ 6 - 3 = -4/ 3

this will be the same no matter which two points you use.

For the y-intercept, plug in a point and solve for b.

y = mx+b

-5= -4/3(9) + b

b= 7

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.
