Find an equation in slope-intercept form (where possible) for the line.
-Through $ (-1,-1.5) $ and $ (3,3.5) $
A) $ y=-1.25 x-2.75 $
B) $ y=1.25 x-0.25 $
C) $ y=-0.8 x-2.3 $
D) $ y=0.8 x-0.7 $

The slope (m) is calculated as $\frac{3.5 - (-1.5)}{3 - (-1)} = \frac{5}{4} = 1.25$. Using point-slope form with point (-1, -1.5), $y + 1.5 = 1.25(x + 1)$, simplifying gives $y = 1.25x - 0.25$.
