Question
Write the equation in point-slope form for the line that contains the points
(0, -2) and (3, 4)
- y - 5 = 2(x + 3)
- y + 5 = 2(x - 3)
- y - 3 = 2(x + 5)
- y + 3 = 2(x - 5)
Hint:
using the points calculate slope
and then using the point and slope to write equation .
The correct answer is: y + 5 = 2(x - 3)
The points (0, -2) and (3, 4).
Slope formula
Step 1 : Substitute points we get slope as
4 - (-2) / 3 - 0
= 6 / 3
= 2
m = 2 , is our slope
Step 2 :Point slope form y - y1 = m (x - x1)
Substitute point (3, 4) and m value.
y -4 = 2 (x -3). is the final equation that we get .
the equation in point slope form
y - y1 = m( x-x1)
where
