Question

Which of the following equations represents a line perpendicular to -6x + 7y = -1 ?

Question 1 options:

30x + 35y = -1


-35x - 30y = -1


-6x - 35y = -1


7x - 6y = -1

Answer 1

The last one, do you know why?

Answer 2

yes i juust figured it out thanx

Answer 3

for an equation ax+by+c=0

a perpendicular line has the equation bx-ay+k=0

now you can see multiply the whole equation too to check out whose skope matches.

(because slope of perpendicular line is negative of reciprocal of the slope of the original line)

so its B!!!!

@no-data i think it ll be B
