**Henry**, Saturday, October 20, 2012 at 4:47pm3. 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.
