Question
Determine whether the equation defines $y$ as a linear function of $x .$ If so, write it in the form $y=m x+b$$$2 x-4 y+9=0$$
Step 1
We can do this by isolating $y$ on one side of the equation. We start by subtracting $2x$ from both sides of the equation: $$2x - 4y + 9 = 0 \implies -4y = -2x - 9$$ Show more…
