What is the slope of the line through (11, -10) and (11, 4)?​

Step-by-step explanation:

Slope of a line between two points is given as (y2 - y1)/(x2 - x1)

Given the points: (11, -10) and (11, 4)

This implies: x1 = 11, x2 = -10, y1 = 11, y2 = 4

Slope = (4 - 11)/(-10 - 11)

Slope = -7/-21

Slope = 1/3

22 dimes and 9 nickels

step-by-step explanation:

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.
