If two systems of linear equations have the same solution set (in other words, the two systems are equivalent), then they must have the same number of equations. a. True
b. False

False.

Step-by-step explanation:

Equivalent systems of equations are those that have the same solutions or roots, although they have different numbers of equations. Equivalent systems of equations must have the same number of unknowns.

In other words, two systems of equations are said to be equivalent when they have the same solutions. Equivalent systems of equations do not have to have the same number of equations, although they do have to have the same number of unknowns.

So, the sentence is false.

range is infinite on both x and y axis positive and negative
