Best of luck!k = 4-The value of k in this condition will be 4.......

need value of k

-

3x + y = - 8

If x = - 4, whatever y equals is k.

3(- 4) + y = - 8

Simplify.

- 12 + y = - 8

y = 4

k = 4

-

Put -4 for x and solve for y:

3(-4) + y = -8
-12 + y = -8
y = 4

Thus, k = 4 and the point is (-4, 4)

Best of luck!

-

Plug it into the equation and solve for k
3(-4) + k = -8
-12 + k = -8
k = 4

-

The value of k in this condition will be 4.

-

3x + y = -8

-12 + k = -8

k = 4

-

3x+y=-8; x=-4
3(-4)+y=-8
-12+y=-8
y=4; y=k

-

y = -3x-8
y = -3(-4) - 8 = k
k = 12-8 = 4

-

Jake let X = - 4 and solve for Y
