Straight Lines
Easymathematics
The equation of line passing through (2, 3) with slope 2 is
Select the correct option:
Solution
Incorrect! Answer:
y - 3 = 2(x - 2)
- Point-Slope Form: The equation of a line with slope m passing through (x1,y1) is y−y1=m(x−x1).
- Insertion: Given m=2 and (x1,y1)=(2,3).
- Apply Formula: y−3=2(x−2).
- Simplification (optional): y−3=2x−4⟹y=2x−1.
