Question

Which simplified equation below represents the equation of the line through the point (4,4) that is perpendicular to x - 3y = -18?'

Answer 1

Answer:

y = -x + 8

Step-by-step explanation:

x-3y = -18

-3y = -x -18

3y = x + 18

m = 1 ( but Product of slope of perpendicular lines is -1 so, M= -1)

y-intercept from (4,4) is

4 = -1 (4 )+ b

b= 8

The equation of the line that passes through the given point  (4,4) is

y =mx +b

y = -1 x + 8
