For all other lines, distance is calculated using the distance formula (Pythagorean theorem to calculate the length of a side of a triangle, a.k.a, the hypotenuse). What reasons can you quit a job and still get unemployment? Also know, how do you find the slope calculator? In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). In mathematics, there are four types of slope and all of these typescan be calculated by using this slope calculator. Once you have solved for the slope of the line running between the two points, you can then formulate an equation that will find the Y value for any X value, using the following formula: Using our first example, you would formulate the line equation as follows: Using the second example, you would formulate the line equation as follows: In the case of a vertical line, the X value would be the same for any Y value.
