A line passes through the points (1, 2) and (3, 1). What is the slope of the line? O
0-1
O2
0-2

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

Slope of the line using points

(1, 2) and (3, 1) is

Slope = 1-2/3-1 = -1/2

Equation of the line using point (1,2)

y - 2 = -1/2(x - 1)

y - 2 = -1/2x + 1/2

y = -1/2x + 1/2 + 2

y = -1/2x + 5/2

Hope this helps you

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

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.
