Question

Which equation is a point slope form equation for line ABAB ?

Answer 1

Point slope form is y-y1=m(x-x1)
but first you must get a slope between two points using $m=\frac{y2-y1}{x2-x1}$
insert (-2,-1) and (6,5) 
$m= \frac{5+1}{6+2} m=\frac{3}{4}$
3/4 is your slope, then put this into point slope form
y+1 = 3/4(x +2)
