Graphing Introduction

Required

Question 1

Graph the ordered pairs from the table.

Instructions

Click the graph tab.
Click on the graph background to add a point. Drag a point or type in x and y coordinates to edit its position. Click on a point to delete it.

Question 2

Calculator the slope from the table.

Question 6

Write the coordinates of point B.

Question 7

Calculate the slope of the line with points (7,10) and (-4,3).

Required

Question 8

What is the slope of this graph? (Remember to reduce- no decimals!)

Dilations

Required

Question 9

A triangle has coordinates at A(-2,0) B(-4,4) and C(1, 6). What are the new locations of the coordinates after a dilation by a scale factor of 4? Show your evidence on your paper test.

A'(-8,4), B'(-16,16), C'(5, 24)

 A'(-8,0), B'(-16,16), C'(4, 24) 

 A'(-4,0), B'(-4,4), C'(4, 6) 

 A'(-4,0), B'(-8,8), C'(2, 12)
