multiply 2nd row by -1 and add to first row
divide the 1st row by 2
multiply the first row by -1 and add to 2nd row
now we know
y+3=0
x-2=0
therefor
y=-3
x=2

Answer:
Divide both sides by 18. The new coefficients will be the reciprocals of the intercepts:
The two intercepts are then 3 and -6.
(I know, dividing by 3 both sides of the equations would have made the whole process way easier).
Alternatively, plug x = 0 to find the y intercept and y=0 to find the x intercept. Either way the graph will look something like the one I'm sketching on paint.
