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

• College Math -

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.
