Hello there!
To graph this equation, you can find the x and y intercepts.
To find the x-intercept, solve...
-3x=24
x=-8
Put a point on the x-axis at -8.
To find the y-intercept, solve...
4y=24
y=6
Put a point on the y-axis at 6.
Now draw a line!
The other person gave you a graph so look at that and I hope my answer helps you!
Best wishes!
