Answer:
Option C) y = -2x - 6
Step-by-step explanation:
<u><em>The correct question is</em></u>
In the xy coordinate plane the slope of line p is 1/2 and its x-intercept is -3. Find the equation of a line that is perpendicular to p and intersects p at is x-intercept.
step 1
Find the slope of a line that is perpendicular to p
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)
we have
----> slope of line p
substitute
----> slope of the line perpendicular to p
step 2
Find the equation of the line that is perpendicular to p and intersects p at is x-intercept
we have
Find the equation of the line in point slope form
substitute
