Step-by-step explanation:
b =-4 (y-intercept)
x =0
m = 0 (the line doesn't have a slope)
y = mx + c
y = 0(0) + (-4)
y = - 4
Answer:29.3
Step-by-step explanation: 88/3
Answer:

Step-by-step explanation:
We are given the two functions:

And we want to find:

So, by substitution, we acquire:

Distribute:

Simplify:

Just like counting imaginary dots on the #s
4+1=5
Kx-3y=k
y=4x+1 ( we will put it in 1st equation )
kx - 3 (4x+1)=k
kx - 12 x - 3 =k
kx - 12 x = k+3
x(k-12) = k+3
x=

Also y=

We can not divide with zero.
k-12=0
k=12For k= 12 equations have no solutions.
