The point slope form or the equation of a line is :
y - y1 = m(x - x1)
First find the slope between the two coordinates:
m = y2-y1/x2-x1
m = 0-4 / 2-(-6)
m = -4 / 8
m = - 1/2
Now create the point slope form / equation of a line:
y - 4 = - 1/2(x - (-6))
y - 4 = - 1/2(x + 6)
OR you can have
y - 0 = - 1/2(x - 2)
