## anonymous one year ago Solve the equation for y 4x -5y = 9 A. Y = 5/4x + 9/4 B. Y = -4x - 9 C. Y = 4/5x - 9/5 D. Y = -5/4x - 5/9

Make the equation $$4x-5y=9$$ to $$y=mx+b$$.

Okay

$$\huge 4x-5y=9$$ Subtract $$4x$$ on both sides. $$-4x+4x-5y=-4x+9$$ Then you'll get $$\huge -5y=-4x+9$$ Now, divide $$-5$$ on both sides. $$\huge \frac{-5y}{-5}=\frac{-4x}{5}+\frac{9}{5}$$.

Okay thank you

So, $$\huge y=\frac{-4x}{-5}+\frac{9}{-5}$$ OR .$$\huge y=\frac{4x}{5}-\frac{9}{5}$$ :D

You're welcome! Just a correction: it should be -5 in my second reply. :)
