Question

Two perpendicular lines intersect at the origin if the slope of the first line is 3,what is the equation of the second line

A) y=-3x
B) y=1/3x
C) y=-1/3x
D) y=1/3x+1

Answer 1

· Perpendicular lines have slopes that are opposite reciprocals of each other

· Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept

If the slope of the first line is 3, the slope of the second line is -1/3. Since the lines intersect at the origin, neither of them have a y-intercept.

Answer:

C) y = -1/3x
