Using EZgraph, graph the following equations; calculate the slope, xintercept, and yintercept, 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.
xIntercept Let y = 0 and calculate x.
yInt. = 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 yaxis.
m = A/B = 2/o = Undefined.
xint. = 4.
yint. = C/B = 4/0 = Undefined.
5. Same procedure as #3.
