The equation of line is 3x - 5y = 15.
For y intercept the value of x is 0.
Substitute 0 for x in the equation to obtain the value of x.
[tex]\begin{gathered} 3\cdot0-5y=15 \\ y=\frac{15}{-5} \\ =-3 \end{gathered}[/tex]So answer is -3.
Simplify the equation in slope intercept form.
[tex]\begin{gathered} -2x+4y=8 \\ 4y=8+2x \\ y=\frac{1}{2}x+2 \end{gathered}[/tex]Slope is 1/2 and y intercept is 2.
