Answer
The increasing order of y intercepts are ${{b}_{2}}>{{b}_{1}}>{{b}_{4}}>{{b}_{3}}$.
Work Step by Step
The y intercepts of the graph are the points on the graph at which it meets the y axis. Its x coordinate is 0. The points of the form $\left( 0,b \right)$ are the $y\text{-intercepts}$. Also, the values on $y\ \text{axis}$ decrease from top to bottom.
It can be seen from the figure that $y\text{-intercept}$ ${{b}_{2}}$ lies above all other intercepts; then ${{b}_{1}}$ lies above ${{b}_{3}}$ and ${{b}_{4}}$ , and ${{b}_{4}}$ lies above ${{b}_{3}}$.
Hence, the $y\text{-intercepts}$ in decreasing order are ${{b}_{2}},\ {{b}_{1}},\ {{b}_{4}},\ {{b}_{3}}$.
