1.)
4x%2B3y=12....easiest way is to find zeros
if x=0...=>...4%2A0%2B3y=12.=>...3y=12=>...y=4
if y=0...=>...4x%2B3%2A0=12.=>...4x=12=>...x=3
x|y
0|4
3|0
graph:
4x%2B3y=12...=>...3y=-4x%2B12=>...y=-%284%2F3%29x%2B4
+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C-%284%2F3%29x%2B4%29+
2.)
y=+-2x%2B1
if x=0...=>...y=-2%2A0%2B1.=>...y=1
if y=0...=>...0=-2x%2B1.=>...2x=1=>...x=1%2F2
x|y
0|1
1%2F2|0
