A linear equation is one in which the power of each of the variables is one.For example: 3x - 5 = 2yor 2.5x + 32*y = sqrt(97)z - 6Although there are powers associated with the numbers in the second example, all the variables are to the power one.The reason for the name is that an equation with n variable, when graphed in n-dimensional space, gives a straight line.A linear equation is one in which the power of each of the variables is one.For example: 3x - 5 = 2yor 2.5x + 32*y = sqrt(97)z - 6Although there are powers associated with the numbers in the second example, all the variables are to the power one.The reason for the name is that an equation with n variable, when graphed in n-dimensional space, gives a straight line.A linear equation is one in which the power of each of the variables is one.For example: 3x - 5 = 2yor 2.5x + 32*y = sqrt(97)z - 6Although there are powers associated with the numbers in the second example, all the variables are to the power one.The reason for the name is that an equation with n variable, when graphed in n-dimensional space, gives a straight line.A linear equation is one in which the power of each of the variables is one.For example: 3x - 5 = 2yor 2.5x + 32*y = sqrt(97)z - 6Although there are powers associated with the numbers in the second example, all the variables are to the power one.The reason for the name is that an equation with n variable, when graphed in n-dimensional space, gives a straight line.
