To find a line's equation, identify two of the points through which the line passes, and then use the "x" and "y" coordinates to find the slope of the line, or the rate at which it climbs or falls. Use the slope to find the line's intersection with the y-axis.
To solve an equation with a calculator that is programmed with the order of operations, enter the exact equation and press the solve or equal button. If the calculator does not have the order of operations, enter the equation pieces based on the proper order of operatio...
A mortgage equation is the mathematical formula that a lender uses in order to determine the borrower's fixed monthly payment to pay off a mortgage loan over a period of time. The lender calculates a mortgage amount using a variety of factors including the total purchas...
Find the slope of the line (m), and the place where the line crosses the y-axis, known as the y-intercept (b), to write the equation in slope-intercept form, y = mx + b. Use the equation to find the y value for any x on that line.
The basic equation for calculating population growth multiplies the population size by the per capita growth rate, which is calculated by subtracting the per capita death rate from the per capita birth rate. This simplistic calculation does not factor in the effects of ...
An equation is a statement declaring that two values are equal. It has an equals sign and expressions on the left and right of the equals sign; the expression on the left and the right are equal.
The center of gravity is calculated using two equations, the x coordinate is calculated by x = sum of (mi * xi) / sum of mi. The y coordinate is calculated as y = sum of (mi * yi) / sum of mi. Sometimes the z coordinate is also calculated.
