Question
Identify any relationships that exist among the lines, and then use a graphing utility to graph the three equations in the same viewing window. Adjust the viewing window so that each slope appears visually correct. Use the slopes of the lines to verify your results.(a) $y=x-8 \quad$ (b) $y=x+1 \quad$ (c) $y=-x+3$
Step 1
The slope of a line in the form $y=mx+b$ is given by the coefficient of $x$. For line (a), $y=x-8$, the slope $m_{1}=1$. For line (b), $y=x+1$, the slope $m_{2}=1$. For line (c), $y=-x+3$, the slope $m_{3}=-1$. Show more…
