The combination of. the tornadoes, severe thunderstorm winds and winds behind the cold front left over 775,000 homes and. businesses without power and about $70 million in damages. April 2014 Page 5 of 16 www.mcswa.com. The following is a list of tornadoes experienced by each county in Michigan.
{(-1, 3), (-2, 5), (-3, 3), (-5, -3)}. To show that the four ordered pairs belong together in a set, we list them with commas in between each and brackets around the group. As with other methods of representing relations, we can check the characteristics of a set of ordered pairs to determine if it is a function.he next table does not represent a function. The x column has two values that are 3, and they correspond to two different values for y. Remember, when a single input can produce multiple outputs, the relation is not a function.
Frequently, a relationship between two quantities is expressed as an equation in two variables. For instance, y = 7 â 3 x is an equation in x and y. An ordered pair (a, b) is a solution or solution point of an equation in x and y if the equation is true when a is substituted for x and b is substituted for y.5 The Graph of an Equation For instance, (1, 4) is a solution of y = 7 â 3 x because 4 = 7 â 3(1) is a true statement.In this section you will review some basic procedures for sketching the graph of an equation in two variables.requently, a relationship between two quantities is expressed as an equation in two variables.
