Question
Given y + 6 = 10 (x - 9), find the point used to write this equation.
- (10, 9)
- (6, -9)
- (-6, 9)
- (9, -6)
Hint:
The line y - y1=m(x - x1) passes through (x1, y1)
The correct answer is: (9, -6)
Given equation is y + 6 = 10(x - 9).
Step1 : The line y - y1=m(x - x1) passes through (x1, y1)
Step 2 : On comparing we get x1 = 9 and y1 = -6 .
So , Point is (9, -6).
point of the line y - y1=m(x - x1)
is (x1, y1) which is used to write the equation .
