Given the equation:
2x - 3y = 3
An equation in function format looks like this:
f(x) = mx + b
To write the equation above in function format, use the following steps:
• Step 1:
Make y the subject of the equation
2x - 3y = 3
Subtract 2x from both sides
2x - 2x - 3y = -2x + 3
-3y = -2x + 3
Divide through by -3
[tex]\begin{gathered} \frac{-3y}{-3}=\frac{-2x}{-3}+\frac{3}{-3} \\ \\ y\text{ = }\frac{2}{3}x-1 \end{gathered}[/tex]• Step 2:
Replace y with f(x)
