Question 27179
You must use the equation (y - y1)= m(x -x1)to solve this problem.  
We know that the line we are looking for is perpendicular to the line
 y = -3x + 1.  
Perpendicular lines have negative reciprocal slopes so our 
slope(m) must equal 1/3. 
 We also know that point (0, 5) is the y intercept. 
 Now we plug into the equation: 
 (y - 5) = (1/3)(x - 0)
 (y - 5) = (1/3)x + 0
  y = (1/3)x + 5 is the equation of the line
