. Find the slope and y-intercept of the line shown below.to10-8--10-8-6-4-2.co6-4-2---2--4--6--8--10-yX4 6 8 10

Answer 1

Given the graph:

Using two points on the line to find the slope, m:

`\begin{gathered} (0,-1),(5,-2) \\ \\ x_1=0,y_1=-1,x_2=5,y_2=-2 \\ \\ m=(y_2-y_1)/(x_2-x_1) \end{gathered}`
`\begin{gathered} m=(-2-(-1))/(5-0) \\ \\ m=-(1)/(5) \end{gathered}`

Thus, the y-intercept and slope, m of the line respectively are:
