Let's assume
x is number of hours worked
y is amount paid
Since, this is linear relationship
We can select any two points
(2,36.50) and (4,73)
so, we can also write as
x1=2 , y1 =36.50
x2=4 , y2=73
Firstly, we can find slope
we can plug values
now, we can use point slope form of line
we can plug values
now, we can solve for y

Answer:
product of the roots= c/a
Step-by-step explanation:
The the two roots(α and β) of the quadratic equation ax²+bx+c=0 as given by shridharacharya formula are
now product of the roots
αβ= ×
use formula (a+b)(a-b)= a^2-b^2 and solve we get
αβ= c/a
therefore product of the roots= c/a
