Use an online website or app, such as MeetWays or WhatsHalfway.com, to determine the halfway point between two cities. Both sites allow you to specify whether you wish to stop at a restaurant or other venue when you reac... More »

The distance between two points is calculated using the distanceÂ formula d = √ (x2 - x1)2 + (y2 - y1)2, where (x1,y1) and (x2,y2) are the coordinates of the two points and "d" indicates the distance. The distance formul... More »

The way to calculate the equation of a line that includes the points (x,y) and (x1, y1) is to plug them into the equation y - y1 = m(x - x1) and solve for m, the slope of the line. The way to convert this to y = mx + b f... More »

Graphing inequalities on a number line requires you to shade the entirety of the number line containing the points that satisfy the inequality. Make a shaded or open circle depending on whether the inequality includes th... More »

The product of two or more non-zero whole numbers is always a whole number itself. Whole numbers are integers like 0,1, 2, 3, 4, 5, and 6. A non-zero whole number follows the set of rules except that it cannot be zero. B... More »
