Slope intercept form is:  y = mx + b
.
11.) 4x + y = 1
subtract 4x from both sides
y = -4x + 1
.
12.) x - y = 6
Add y to both sides
x = y + 6
Subtract 6 from both sides
x - 6 = y
y = x - 6
.
13.) 6 x - 3 y = -9
subtract 6x from both sies
-3y = -6x - 9
divide both sides by -3
y = 2x + 3
.
14.) -12 x - 4 y = 2
Add 12x to both sides
-4y = 12x + 2
Divide both sides -4
y = -3x - 1/2
.
15.) 2 x + 5 y = -10
Subtract 2x from both sides
5y = -2x -10
Divide both sides by 5
y = -2/5x -2
.
16.) -x - 10 y = 20
Add x to both sides
-10y = x + 20
Divide both sides by -10
y = -1/10x -2
