## Solutions to Try Its

1. x-intercept is $\left(4,0\right)$; y-intercept is $\left(0,3\right)$.

2. $\left(-5,\frac{5}{2}\right)$

## Solutions to Odd-Numbered Exercises

1. Answers may vary. Yes. It is possible for a point to be on the x-axis or on the y-axis and therefore is considered to NOT be in one of the quadrants.

3. The y-intercept is the point where the graph crosses the y-axis.

5. The x-intercept is $\left(2,0\right)$ and the y-intercept is $\left(0,6\right)$.

7. The x-intercept is $\left(2,0\right)$ and the y-intercept is $\left(0,-3\right)$.

9. The x-intercept is $\left(3,0\right)$ and the y-intercept is $\left(0,\frac{9}{8}\right)$.

11. $y=4 - 2x$

13. $y=\frac{5 - 2x}{3}$

15. $y=2x-\frac{4}{5}$
