We need to count how many are longer than 7. There are 4 leaves that are 7 inches long. 3 are 8 inches long. 1 in 9 inches long. Adding these up gives us our answer. Let x be the leaves 7 inches or longer.
In this case, the degree of variable y is 1 , the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not a linear equation.
