You've got 2 equations and 2 unknowns. Your line can be written as an equation of the form y = mx + d. Now you know 2 points (6, -3) and (-4, -9) that satisfy this equation. Substitute x= 6 and y= -3 into y=mx + d to get the first equation, substitute x=-4, y= -9 to get the second equation:
\[y= mx + d\]\[1) -3 = m\cdot 6 + d\]\[2) -9 =m\cdot (-4) + d\]
