Chapter 1 - Linear Functions - 1.3 Fundamentals of Graphing and Slope - 1.3 Exercises - Page 53: 84

Answer

The graph is shown below.

Work Step by Step

The given linear equation is $\Rightarrow y=-0.3x+6$ For the vertical intercept plug $x=0$. $\Rightarrow y=-0.3(0)+6$ Simplify. $\Rightarrow y=6$ The vertical intercept is $A=(0,6)$ Slope is $m=-0.3=\frac{-3}{10}$, so the rise is $-3$ when the run is $10$. Starting at $(0,6)$ and going down $3$ and over $10$, we get to $B=(10,3)$. Repeat the same to get the next point $C=(20,0)$. By using theses three points draw a line.
