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:
