Find the y-intercept of the function 3x + 5y = 15.

Solution:
Given;
[tex]\begin{gathered} 3x+5y=15 \\ \end{gathered}[/tex]Make y the subject of the equation;
[tex]\begin{gathered} 5y=-3x+15 \\ \\ y=-\frac{3}{5}x+\frac{15}{5} \\ \\ y=-\frac{3}{5}x+3 \end{gathered}[/tex]
The y-intercept of the function is;
[tex]y=3[/tex]
