You have to get each term on one side. first, add 18 to both sides. your equation is now x-4y-18. then add 4y to both sides. you now have x-18=4y. then divide both sides by 4. your equation is now (x-18)/4=y, and you can now put in values for x to plot points.
Answer:
y=2x+7
Step-by-step explanation:
If you plug in the x and y values, they are correct.
Answer:
D) (x^-3*y^-12)/(x^15*y^-15)
Step-by-step explanation:
If you simplify that further, then you'll get x^(-18)*y^3.
