Answer:

y = -1/3 x + 2

Explanation:

Perpendicular

Two lines that a perpendicular have slopes that multiply to minus 1.

Given line: The slope is 3. Find the slope of a line perpendicular to the given one.

m1 = 3

m2 = ?

m1 * m2 = - 1

3 * m2 = - 1

m2 = - 1/ 3

Y intercept of -x + 5y= 10

The y intercept occurs when x = 0

x = 0

y = 2

The y intercept = (0,2) This is the point you use to determine the equation.

y = mx + b

y = -1/3 x + b

when x = 0 , y = 2

2 = -1/3(0) + b

b = 2

Line equation

Answer: y = -1/3 x + 2
