Elimination Method Quiz

What is the primary goal of the elimination method when solving systems of equations?

• To eliminate one variable by adding or subtracting equations

• To convert equations to slope-intercept form

• To find the slope of the line

• To graph the equations

When aligning equations for the elimination method, what form is preferred?

• Slope-intercept form

• Point-slope form

• Standard form

• Quadratic form

In the elimination method, what should you do if the coefficients of a variable are the same but opposite?

• Divide the equations

• Multiply the equations

• Subtract the equations

• Add the equations

What is the ordered pair solution for the system: 2x + y = 7 and 3x - y = 8?

• (3, 1)

• (2, 5)

• (1, 3)

• (4, -3)

What is the first step when using subtraction in the elimination method?

• Multiply one equation by negative one

• Add the equations

• Divide the equations

• Convert to slope-intercept form

How do you handle equations that are not initially aligned in the elimination method?

• Convert to a different form

• Rearrange the equations to align variables

• Use a calculator

• Ignore the misalignment

If you have the equations 4x + 2y = 8 and 4x + 3y = 10, what should you do to eliminate x?

• Multiply both by 2

• Add the equations

• Divide both by 4

• Subtract the equations

What should you do if you end up with a statement like '0 = -2' after eliminating variables?

• Conclude there is no solution

• Recalculate the equations

• Check for calculation errors

• Assume infinite solutions

What is the result when both variables are eliminated and the remaining statement is false?

• The system has no solution

• The system has one solution

• The system has infinite solutions

• The system needs to be recalculated

What is the solution for the system: 6x + y = 7 and 6x + y = 9?

• Need more information

• Infinite solutions

• One solution

• No solution
