Question

What is the slope of the line passing through (3,-4) and perpendicular to the line y=3x+5?

Answer 1

if it's perpendicular to 3x, then it must be -1/3

Answer 2

well m would be 1/-3

just plug in 3 and -4 and solve for y next

Answer 3

-4=1/-3 * 3+b

solve for b

Answer 4

b=-3

so it be

y=1/(-3) * x + -3
