On this line, what is the x-coordinate of the point whose y-coordinate is 500? A. 249 B. 498 C. 676 D. 823 E. 1,002 The OA is A The question conveniently gives us the information to write the equation of the line in slope y-intercept form, y = mx + b, where m = slope and b = the y-intercept. Line in the xy-plane has a slope of 2 and a y-intercept of 2 So, the equation of the line is: y = 2x + 2 On this line, what is the x-coordinate of the point whose y-coordinate is 500? To find the corresponding x-value, we'll take the equation y = 2x + 2 and replace y with 500 We get: 500 = 2x + 2 To solve for x, first subtract 2 from both sides to get: 498 = 2x Solve: x = 498/2 = 249 Answer: A Cheers, Brent _________________ Brent Hanneson â€“ Creator of GMATPrepNow.com Use my video course along with Sign up for free Question of the Day emails And check out all of these free resources GMAT Prep Now's comprehensive video course can be used in conjunction with Beat The GMATâ€™s FREE 60-Day Study Guide and reach your target score in 2 months! ### Top Member Legendary Member Joined 29 Oct 2017 Posted: 965 messages Followed by: 4 members The slope of 2 and a y-intercept of 2, y-coordinate is 500 $$y = 2x + 2 \\ 498 = 2x \\ x = 249$$ • FREE GMAT Exam Know how you'd score today for$0
