2 Warm Up

3 Question 1 Does the following table represent a linear relationship? If so what is the rate? and write an equation. XY

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

5 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

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

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

8 Answers: 1. Yes, rate: -6, equation: y = -6x Decreases by 2 4. C
