Graph the set of points. Which model is most appropriate for the set?
Tamiku [17]
Check the slope between the moving points 

<span>slope between (–6, –1) & (–3, 2) = 1 </span>
<span>slope between (-3, 2) & (–1, 4) = 1 </span>
<span>slope between (-1, 4) & (2, 7) = 1 </span>

<span>the points are collinear and make an angle of 45 degrees with the x-axis </span>

<span>we can have an equation of a line passing through (-6,-1) and slope 1 as </span>

<span>(y + 1) = 1(x + 6) </span>
<span>y = x + 5 is your linear model mostly</span>
