What is the solution to a system of equations when graphed?

• They're Parallel

• The Intersection

• The Slope

• The y-intercept

What is the new method we are learning today?

• Elimination

• Trial and error approach
• Intuitive decision-making
• Random guessing technique

What do you do with the equations to eliminate one of the variables?

• Add the variables together
• Ignore one of the equations
• Use substitution or elimination methods.
• Add the equations together

When you solve for the first variable, what do you do with its value?

• Ignore the value and move to the next variable.
• Substitute its value back into the equation.
• Delete the value from the equation.
• Use the value to solve for a different variable.

If you cannot cancel terms at the start, what can you do to one of the equations?

• Swap the equations without changing their values.
• Add a constant to both sides of the equation.
• Multiply one of the equations so the terms can cancel each other out

• Multiply both equations by zero.

What can you do with none of the coefficients cancel?

• You must eliminate all variables present.
• You can only evaluate the expression numerically.
• You can ignore the expression entirely.
• You must multiply them by each other (and make one negative).

What is the elimination method?

• A technique for graphing linear equations.
• A method for solving systems of linear equations by eliminating variables by adding them together.

• A method for finding the roots of polynomial equations.
• A strategy for maximizing profit in business calculations.
