Using EZgraph, graph the following equations; calculate the slope, x-intercept, and y-intercept, and label the intercepts on the graph.

3. 4.9x – 7.2y = 2.3

4. 2x = -8

5. 3.7x + 4.2y = 5.03

3. 4.9x - 7.2y = 2.3.

m = -A/B.
x-Intercept Let y = 0 and calculate x.
y-Int. = C/B.
OR Let x = 0 and calculate y.

4. 2x = -8.
X = -4.
This is a ver. line., and it is 4 units to the left of the y-axis.
m = -A/B = -2/o = Undefined.
x-int. = -4.
y-int. = C/B = -4/0 = Undefined.

5. Same procedure as #3.

3x-9=3y

To graph the given equations and calculate the slope, x-intercept, and y-intercept, we can use the EZgraph website. Here's how to do it:

1. Open a web browser and go to the EZgraph website (www.ezgraph.com).

2. On the EZgraph homepage, you will see a graphing calculator interface. Locate the equation input box and enter the first equation: 4.9x – 7.2y = 2.3. Make sure to separate the variables by using a space.

3. Press the "Graph" button to plot the equation on the graph.

4. To find the slope, x-intercept, and y-intercept, observe the graph. The slope can be determined by the steepness of the line. The x-intercept is the point where the line crosses the x-axis (where y = 0), and the y-intercept is the point where the line crosses the y-axis (where x = 0).

5. Using the information obtained from the graph, label the x-intercept and y-intercept on the graph by marking the corresponding points.

6. Repeat steps 2-5 for the other two equations (2x = -8 and 3.7x + 4.2y = 5.03) by entering them into the equation input box one at a time and graphing them.

By following these steps, you should be able to graph the equations, calculate the slope, x-intercept, and y-intercept, and label the intercepts on the graph using EZgraph.
