Option D:
The equation of a line in point-slope form is y = 3x – 7.
Solution:
Take any two points on the line given in the graph.
Let the points be (–4, 4) and (2, 2).
Slope of the given line:
<em>If two lines are perpendicular, then the product of their slopes are –1.</em>
Multiply by 3 on both sides of the equation.
Multiply by –1 on both sides of the equation.
⇒
Perpendicular line passes through the point (2, –1).
Here, .
Using point-slope form:
Subtract 1 on both sides of the equation.
The equation of a line in point-slope form is y = 3x – 7.
Therefore option D is the correct answer.
