Question:

The equation of a straight line on a point (3, -5) and slope 2 is :

Options:

2x - y - 11 = 0

3x - 5y - 2= 0

5x - 2y + 3 = 0

3x - 2y - 5 = 0

Correct Answer:

2x - y - 11 = 0

Explanation:

We know that,

(y - y1) = m(x - x1)

m = slope of a line, and (x1, y1)

We have,

The equation of a straight line on a point (3, -5)

The slope of a line = 2.

 x1 = 3, y1 = -5

According to the formula ,

= y - (-5) = 2 × (x - 3)

= y + 5 = 2x -6

= 2x - y - 11 = 0
