Answer:

  zero

Step-by-step explanation:

Dividing the second equation by -3, it becomes ...

  x -3y = 7/3

Compared to the first equation, ...

  x -3y = 5

we see that it is <em>inconsistent</em>. No values of the variables can satisfy both equations. There are no solutions.

A slope of (12) and goes through point (10,-5).<br><br> What’s the intercept ?
Advocard [28]

Answer:

the answer is -125

Step-by-step explanation:

we know:

y=mx+c

as m(slope)=12 and(x,y)=(10, -5)

so by putting the values in the equation we get,

-5=12X10+c

or, -5-120=c

or, c=-125

ANS= -125
