Question
Given y-1=-5(x-2), _______ point used to write this equation.
- (-1, 9)
- (6, -9)
- (-2, 9)
- (2, 1)
Hint:
Given the equation in point slope form
y - y1 = m( x-x1)
the point will be ( x1 , y1 ) .
The correct answer is: (2, 1)
Given equation is y -1 = -5 (x - 2).
Step 2 : in point slope form
y - y1 = m( x-x1)
the point will be ( x1 , y1 ) .
Step 2 : On comparing
x1 = 2 and y1 = 1
So , Point is (2,1).
Make the equation in point slope form if it is not in the form .
