Question
For the line y - 3 = 2(x + 4), the slope is 2 and passes through the point _______.
- (-4, 3)
- (3, -4)
- (-3, -4)
- (-4, -3)
Hint:
The line y - y1=m(x - x1) passes through (x1 , y1 ) .
The correct answer is: (-4, 3)
Given equation is y - 3 = 2(x + 4)
we can rewrite as y - 3 = 2( x - (-4) )
The line y - y1=m(x - x1) passes through (x1 , y1 ) .
Step 1 : x1 = -4
step 2 : y1 = 3
So , the Point is (-4,3)
the line will pass through ( x1 , -y1 ) .
