Question
Write the equation in point-slope form for the line that contains the points
(-2, -3), (4, 3)
- y - 3 = 1(x - 2)
- y + 3 = 1(x + 2)
- y -3 = -1(x + 2)
- y + 3 = -1(x - 2)
Hint:
, where m is the slope and ( x1 , y1 ) and ( x2 , y2 ) are points
Point-slope form of equation of a line is y - y1 = m (x - x1)
The correct answer is: y + 3 = 1(x + 2)
Given points are (-2, -3), (4, 3)
Step 1 : calculating Slope
Slope
=
=1
Step 2 : Point-slope form of equation of a line is y - y1 = m (x - x1)
A line that passes through point (-2, -3) and has slope 1 is
y + 3 = 1(x + 2) , is the equation of the line .
Point-slope form of equation of a line is y - y1 = m (x - x1)
