Find the slope of a line through the points (-6, -2) and (-4,-5).
Select the best answer from the choices provided.
A 3/2
B -3/2
C -2/3
D 2/3

B

Step-by-step explanation:

Slope = (y2-y1)/(x2-x1)

= (-5-(-2))/(-4-(-6))

= (-5+2)/(-4+6)

= -3/2

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.

i saw this question before, dont know the asnwer srry
