How do I find the slope and y intercept of y=4x-4

slope: 4

y intercept: -4

Step-by-step explanation:

the equation you're given is in y = mx + b format

the "b" in the equation is the y intercept

the x and y are the variables

and the "m" is the slope

so in this case, the "m" would be 4 because it is the number right next to x

the -4 would be the "b" in this because it is after the "y=" and does not have a variable

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.
