Answer:
The slope of the line 
The point ( x₁ ,y₁) = ( 2,1)
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the line

Comparing y- y₁ = m(x-x₁)
The slope of the line 
The point ( x₁ ,y₁) = ( 2,1)
The equation of the straight line

2(y-1) = -(x-2)
2y -2 = -x +2
x + 2y -2-2=0
x +2y -4=0
<u><em>Final answer:-</em></u>
The equation of the straight line x+ 2y-4=0
The slope of the line 
The point ( x₁ ,y₁) = ( 2,1)
