Given data:
The given equation of the line is 3x+6y=-18.
The x-intercept is the point where the graph cuts the x-axis.
Substitute 0 for y in the given equation.
3x+6(0)=-18
3x=-18
x=-6
The y-intercept is the point where the graph cuts the y-axis, substitute 0 for x in the equation.
3(0)+6y=-18
6y=-18
y=-3
Thus, the x intercept is -6, and y intercept is -3.
Now draw a line which is passes through (-6,0) and (0,-3).
