Question 120521
Remember that lines which are perpendicular to each other have slopes which are negative reciprocals of each other. So the slope of the line they are asking you for is the negative reciprocal of -3, which is 1/3. They are giving you the Y-intercept, so now it is easy to write out the equation of the line in slope/intercept form as follows:
{{{highlight(y=x/3+5)}}}
