To fill the blanks with the appropriate word for the statement: The form which has stair-step pattern with leading coefficients of 1.

Answer to Problem 1E
The system of equations in row-echelon form has a stair-step pattern with leading coefficient of 1
Explanation of Solution
Method of elimination can be applied for more than one variable. This elimination is also used in computer to solve the system of linear equations. The system of linear equation can be converted into row-echelon form for the use of elimination method. An example of row echelon conversion is shown below:
Thus, the second system is in row-echelon form, which means that it has a stair-step patterns.
