Which of the following lines has x-intercept and y-intercept that are integers? A. y=3x+1 B. y=√x+1 C. y=-2/x D. y=x^2-1 E. xy=1

*An answer will be posted in 2 days.

IMPORTANT POINT #1: The y-intercept is the point where the x-coordinate is 0 So, let's plug x = 0 into each answer choice. We get: A. y= 3(0) + 1 = 1. Integer - KEEP B. y = √0 + 1 = 1. Integer - KEEP C. y = -2/0 undefined. ELIMINATE D. y = 0² - 1 = -1. Integer - KEEP E. (0)y = 1. When we solve for y, y is undefined. ELIMINATE

We're left with A, B and D IMPORTANT POINT #2: The x-intercept is the point where the y-coordinate is 0 So, let's plug y = 0 into each answer choice. We get: A. 0 = 3x + 1 Solve to get x = -1/3. Not an integer. ELIMINATE B. 0 = √x + 1 Unsolvable for x. ELIMINATE D. 0 = x² - 1 x = 1 or -1, Both are integers. KEEP!

This is a super flop question because there are many options given that don't qualify to be a line or line segment.

I'd call them all lines but not STRAIGHT LINES.

Is it the case in GMAT that a line implies a straight line?

Really? You also call Parabola a Line? D. y=x^2-1

The Mathematics THAT I have learned so far lines are default straight in nature. I have never Know a Line that is curvical or conical or perhaps spherical.
