We are asked to find a system of equations with (- 4, - 12) as its solution. For our first equation, we can choose any arbitrary slope and then substitute it, together with x= - 4 and y= - 12, in the general formula for the slope-intercept form of a line. Let's choose a slope of 2.
We can find the second equation in the same way, as long as we do not choose the same slope! Let's now choose a slope of 5. Again, we know the line passes through ( - 4, - 12), and so this becomes our point.
