Question 1 Does the following table represent a linear relationship? If so what is the rate? and write an equation. X Y 45 1 39 4 21 6 9 7 3 -9 11 -21

What is the y-intercept in the following equation? Y = 4.5x + 25
Question 2 What is the y-intercept in the following equation? Y = 4.5x + 25

Question 3 The following equation represents a linear relationship between x and y. Describe what happens to the y value as the x value increases by 1. y = -2x + 15

What is occurring at the intersection point of two linear equations?
Question 4 What is occurring at the intersection point of two linear equations? The y- coordinate is increasing. The x- and y- coordinates are different on both graphs. The x- and y- coordinates are the same on both graphs. The x- coordinate is increasing.

Time is up!!! You have 45secs to trade papers!

Answers: Yes, rate: -6, equation: y = -6x+45 25 Decreases by 2 C
