to find the slope m and y intercept, first write your equations in +slope-intercept form: y=mx%2Bb where m is a slope and b is y-intercept
1.
-3-12y=4x+
-3-4x=12y+
-3%2F12-%284%2F12%29x=y+
-1%2F4-%281%2F3%29x=y+ or
y=-%281%2F3%29x-1%2F4
so,m=-%281%2F3%29 and b=-1%2F4
+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C+-%281%2F3%29x-1%2F4%29+

2.
5y%2B25=4x
5y=4x-25
y=%284%2F5%29x-25%2F5
y=%284%2F5%29x-5
here,m=%284%2F5%29 and b=-5

+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C%284%2F5%29x-5%29+
3.
6y-3=38x
y=%2838%2F6%29x%2B3%2F6
y=%286.33%29x%2B1%2F2
here,m=6.33 and b=1%2F2=0.5
+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C%286.33%29x%2B1%2F2%29+
4.
%281%2F2%29x%2B%283%2F2%29y=1
%283%2F2%29y=-%281%2F2%29x%2B1...both sides multiply by 2
2%283%2F2%29y=-%281%2F2%292x%2B1%2A2
3y=-1x%2B2
y=-%281%2F3%29x%2B2%2F3
and here,m=-%281%2F3%29 and b=2%2F3

+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C-%281%2F3%29x%2B2%2F3%29+
