A.
B.
C.
D.
To choose the correct option for given conditions.
Answer to Problem 3STP
Option C is correct.
Explanation of Solution
Given information:
Equation passes through (-10, 3) and is perpendicular to
Standard equation of line is,
Where m is the slope of the line.
Now we know that when two lines are perpendicular then the product of their slopes is -1.
Slope of given line is 5.
Hence the slope of required line is
Now we shall put the values of points and slope we get equation as,
Option C is correct.
