Rewrite the equation in the slope-intercept form. Then identify the slope and the y-intercept of the line...
11.) 4 x + y = 1
12.) x - y = 6
13.) 6 x - 3 y = -9
14.) -12 x - 4 y = 2
15.) 2 x + 5 y = -10
16.) -x - 10 y = 20

.
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
You can put this solution on YOUR website! Use the y=mx+b form
m=the slope
b=the y-intercept
11.) 4 x + y = 1
4x-4x+y=-4x+1
y=-4x+1
Slope =-4
y-intercept=1
12.) x - y = 6
x-x-y=-x+6
-y=-x+6 =
y=x-6
so,
slope=1
y-intercept=-6
14.) -12 x - 4 y = 2
-12x+12x-4y=12x+2
-4y=12x+2 =(12x/-4)+(2/-4)
y=-3x-1/2
so,slope=-3
y-intercept=-1/2
15.) 2 x + 5 y = -10
2x-2x+5y=-2x-10
5y=-2x-10 =
y=
so,
slope =-2/5 and y-intercept=-2
16. -x - 10 y = 20
-x+x-10y=+x+20
-10y=x+20 =
y=-1/10)x-2
so,
slope=-1/10
y-intercept=-2
