Hi ,
If x - intercept and slope of a given
line is equal .
We put y = 0 in the equation we get
x - intercept.
3x + k = 0
x = -k/3 ---( 1 )
Slope of a line( m )= - 3/( -1 ) = 3 ---( 2 )
( 1 ) = ( 2 )
- k/3 = 3
k = - 9
I hope this helps you.

Answer:
In this question,
slope and x-intercept is given,
line is 3x-y+k=0,
slope= -(a/b)=3-----(1)
and x-intercept, y=0
so equation is 3x+k=0
x = -(k\3)------(2)
from eqn 1&2
k = -9
