Question

Which of the following equations represents a line perpendicular to -5x + 3y = 1?
Question 38 options:
3x - 5y = 1

30x + 50y = 1

-50x - 30y = 1

-5x + 30y = 1

Answer 1

Find the slope of the first line and then find the reciprocal. Once you do this find the line with the reciprocal in it as the slope.

Answer 2

perpendicular lines have opposite reciprocals.
one must be positive and the other negative
a and 1/a
