The slope and y-intercept of the given equation $y=\frac{2}{5}x-1$ of the line is $\frac{2}{5}$ and -1.
The given equation of the line is $y=\frac{2}{5}x-1$ Compare the given equation with the general slope-intercept form: $y=mx+c$ Slope $=\frac{2}{5}$ Now, to find the y-intercept, substitute $x=0$ in the given equation: \begin{align} & y=\frac{2}{5}\left( 0 \right)-1 \\ & y=-1 \end{align}
