Which of the following does not describe slope? a line joining points a constant rate of change a proportional relationship a measure of change

A. A line joining points.

Step-by-step explanation:

The following does not describe slope:

A line joining points.

Slope is found by dividing the difference of the y-coordinates of two points on a line by the difference of the x-coordinates of those same two points.

Or in other words, it is defined as the ratio of the vertical change between two points to the horizontal change between the same two points.

its electric no smoke

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.
