Eliminate the parameter with two linear equations

What is the main goal when eliminating a parameter in a mathematical equation?

• To simplify the equation by removing a variable

• To introduce a new variable

• To change the equation's graph

• To add complexity to the equation

When solving for T, which equation is typically used first?

• The equation for W

• The equation for X

• The equation for Y

• The equation for Z

What is a common method to eliminate the parameter T?

• Multiplying all terms by T

• Adding a new variable

• Substituting T into another equation

• Graphing the equation

In the example provided, what is the expression for T?

• T = X + 3 = 2

• T = Y - 4 = 2

• T = Z + 5 = 3

• T = W - 2 = 1

What is the final algebraic expression for Y after eliminating T?

• Y = 12 + 6(X - 1)/3

• Y = 8 - 3(X + 2)/5

• Y = 5 + 2(X - 3)/4

• Y = 10 - 4(X + 3)/2
