Bellwork 3/27/18 1.) Which of the following is NOT rational? 16.3333333…… 14/7 19.2 𝟏𝟗𝟐 2.) Do these points represent a function? (1,2)(3,5)(7,15) 3.) What is the slope between these two points? ( 2, 8) and (-12, 6)

Finding Slope From 2 points: 𝒚−𝒚 𝒙−𝒙 From a Graph: 𝑹𝒊𝒔𝒆 𝑹𝒖𝒏 From a Table: Find the pattern OR Pick 2 points & do 𝒚−𝒚 𝒙−𝒙

1.) Find the slope between the points (-1, 0) and (4, 6)

2.) Find the slope of the table x y 3 -2 4 5 2 6

3.) Find the slope of the graph

How to find the y-intercept Points: Look for zero as the x value ex. (0, B) Graph: Look for where the line crosses the y-axis Table: same as points…look for (0, B)

Slope-Intercept form Equations Y= mx+b M= slope B= y-intercept

4.) Write a slope-intercept form equation for the graph.

5.) Which equation matches the table? x y -6 7 -3 14 21 3 a.) y= 𝟕 𝟑 x-6 c.) y= 𝟑 𝟕 x+14 b.) y= 𝟑 𝟕 x-6 d.) -6x + 14
