<h3> Interval: (-infinity,4]</h3>
Answer:
Take two point from the table, doesn't matter which ones, because this is linear. I will choose (0,0) and (3,.5).
Now follow the equation for slope: m = change in y / change in x.
![\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
![\frac{.5-0}{3-0}](https://tex.z-dn.net/?f=%5Cfrac%7B.5-0%7D%7B3-0%7D)
![\frac{.5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B.5%7D%7B3%7D)
![\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D)
The slope is 1/6. m=1/6
Its y-intercept is at 0. b=0
So the equation is y = 1/6x. The graph is attached.
