##### Graph Set 1:

Graph the following four lines on one coordinate plane using Desmos.com. For information on how to graph multiple equations using Desmos, view the Demonstration of Desmos.com Graphing Tool . Be sure to associate the line label to the color of the graph on Desmos.

Line A:* *\(y=\frac{2}{5}x\)

Line B:* \(y=\frac{3}{4}x\) *

Line C:* \(y=\frac{5}{3}x\) *

Line D:* \(y=4x\)*

1. Which word best describes the slopes of these lines?

*positive negative *

2. Which phrase best describes how these lines point from left to right?

*up to the right down to the right*

3. Fill in the blanks: Lines that have __ __ slopes point __ .__

##### Graph Set 2:

Graph the following four lines on one coordinate plane using Desmos.com. Be sure to associate the line label to the color of the graph on Desmos.

Line A:* *\(y=-\frac{1}{5}x\)

Line B:* \(y=-\frac{2}{7}x\) *

Line C:* \(y=-\frac{4}{5}x\) *

Line D:* \(y=-2x\)*

1. Which word best describes the slopes of these lines?

*positive negative*

2. Which phrase best describes how these lines point from left to right?

*up to the right down to the right*

3. Fill in the blanks: Lines that have __ __slopes point __ .__
