Exploring Reflections in Linear Equations

What operation can you perform on a positive number to find its opposite?

• Add 1

• Multiply by -1

• Subtract 1

• Divide by 2

If X is -7, what is the result of multiplying X by -1?

• -7

• -1

• 0

• 7

What is the slope of the function F(x) if it increases by 2 for every increase in X by 1?

• 1

• 2

• -2

• 0

How can you express the function G(x) if it is a reflection of F(x) across the X axis?

• G(x) = F(x)

• G(x) = -F(x)

• G(x) = F(-x)

• G(x) = 2F(x)

When reflecting across the Y axis, what happens to the X coordinates?

• They remain the same

• They become opposites

• They double

• They become zero

What is the algebraic representation of a function with a slope of 3 and a Y intercept of 2?

• F(x) = 3x + 2

• F(x) = -3x + 2

• F(x) = 3x - 2

• F(x) = 2x + 3

If the Y intercepts of two functions are the same, what can be said about their reflections?

• They are parallel

• They have the same slope

• They have opposite slopes

• They are identical
