Chapter 5 - Linear Functions - 5-3 Slope-Intercept Form - Practice and Problem-Solving Exercises - Page 310: 14

Slope: $-0.2$ $y$-intercept: $3$

The slope-intercept form of a linear equation of a non vertical line is $y=mx+b$, where $m$ is the slope and $b$ is the $y$-intercept. We use this to pick out the slope and the $y$-intercept from the equation $y=-0.2x+3$. Since $-0.2$ takes the place of $m$ in the equation, it is the slope. Since $3$ takes the place of $b$ in the equation, it is the $y$-intercept.
