Question

]Let c be any constant number. Which of the following will always be perpendicular to −3x + y = 2

y = 3x + c

y =1/3 x + c

y = −3x + c

y = -1/3 x + c

Answer 1

HELP PLEASE

Answer 2

use the fact that the product of the slopes of two perpendicular lines is always -1

Answer 3

so first, what is the slope of the line given by:
-3x + y = 2
