A. 2 B. 0 C. 1/2 D. 1 E. 2 The line x = 2y + 5 passes through points (m,n) and (m + 2,n + p) means that m=2n+5 and m+2=2(n+p)+5. Now, subtract the first equation from the second: (m+2)m=2(n+p)+5(2n+5) > 2=2p > p=1. Answer: D.

Another way: Slope of the line can be calculated...
y=mx+c => y= (1/2)x5/2 => 1/2=n+pn/m+2m =>1/2=p/2 => p=1

Hi All, When dealing with a graphing question, it often helps to convert any equations you've been given into "slopeintercept" format (and you might find it helpful to physically draw the graph so you can see it). Here, we're given the line X = 2Y = 5. Converting that into slopeintercept gives us: 2Y = X  5 Y = X/2  5/2 We're then told that the line passes through the points (M,N) and (M+2,N+P). We're asked for the value of P. Since we have the line, we can TEST a set of coordinate for (M,N) IF..... X = 0 Y = 5/2 So (M,N) is the point (0, 5/2) The second point is (M+2,N+P) Since our M = 0......M+2 = 2..... we have to see what happens when.... X = 2 Y = 1  5/2 = 3/2 So (M+2,N+P) is the point (2, 3/2) So between the first point and the second point, what has happened to the Y coordinate? It went from 5/2 to 3/2, so it INCREASED by 1. Thus, P = 1 Final Answer: GMAT assassins aren't born, they're made, Rich

A. 2 B. 0 C. 1/2 D. 1 E. 2 Rewrite x = 2y + 5 like so: y = 0.5X + 2.5 Plug in Values for m = x: if m = x = 1, the first point is 1, 3 if m = x = 3, the second point is 3, 4 Therefore n = 3 and n + p = 4. p = 1

A. 2 B. 0 C. 1/2 D. 1 E. 2 If 2y+5=x then, 2y=x5 or \(y=\frac{x}{2}\frac{5}{2}\) Now this has become the equation of line in the point slope form. {y=mx+b} slope (m) is 1/2 and we also know Slope (m)=\(\frac{y2y1}{x2x1}\) threfore putting the value of x and y from the question we get \(\frac{n+pn}{m+2m} = \frac{1}{2}\) \(\frac{p}{2}=\frac{1}{2}\) ===> p=1 ANSWER IS D

You focus on very simple methods of breaking problems down. I'm not quite an assassin yet but I have to be soon. Thanks for the help. Posted from GMAT ToolKit

A. 2 B. 0 C. 1/2 D. 1 E. 2 Since the line x = 2y + 5 passes through points (m,n) and (m + 2,n + p) we have m=2n+5  I m+2=2(n+p)+5.  II solving I and II we have p =1 Hence option D is correct.

A. 2 B. 0 C. 1/2 D. 1 E. 2 We are given that line x = 2y + 5 passes through points (m,n) and (m + 2,n + p). Thus, we can make two equations and substitute m and m + 2 for x, and n and n + p for y. Equation 1: The ordered pair (m,n) means that x = m and y = n. Substitute these values into the equation x = 2y + 5. m = 2n + 5 Equation 2: The ordered pair (m + 2,n + p) means that we will let x = m + 2 and y = n + p. m + 2 = 2(n + p) + 5 m + 2 = 2n + 2p + 5 m = 2n + 2p + 3 We can equate equations 1 and 2 and we have: 2n + 5 = 2n + 2p + 3 5 = 2p + 3 2 = 2p p = 1 Alternate solution: We are given that line x = 2y + 5 passes through points (m,n) and (m + 2,n + p). We can find the slope of the line by isolating y: x = 2y + 5 2y = x  5 y = 1/2x  5/2 Thus, the line has slope 1/2. For any two points on this line, the slope between these two points must be 1/2 also. Since (m,n) and (m + 2,n + p) are on the line, the slope of the line connecting them must be 1/2. Therefore, using the slope formula, which is slope = (change in y)/(change in x), we have: (n + p  n)/(m + 2  m) = 1/2 p/2 = 1/2 p = 1 Answer: D

Hi pushpitkc how is your gmat prep ? hope bumpy roads, pit stops are already behind you, and there is just highway in front of you can you break down Bubuel`s solution please i dont understand how from here x = 2y + 5 passes through points (m,n) and (m + 2,n + p) he concludes that that m=2n+5 and m+2=2(n+p)+5. i can replace (m,n) and (m + 2,n + p) with x, y, p for example (x,y) and (x + 2, y + p) have a great weekend
