What is the equation represented in the line graphed below?

Write the equation of a line perpendicular to y=-5x that passes through the point (1,1) in slope intercept form. (This question is worth 2 points. One point for the correct slope and the second point is for the correct y intercept.)

Aviation The Federal Aviation Administration tracks airline delays for airports around the country. During the first half of 2007, the flights delayed at Dallas-Fort Worth Airport averaged 4,500 per month. Use this information to write an equation in slope-intercept form that could be used to predict the total number of delays throughout the year. Let x equal the month of the year and y equal the cumulative delays.
