Answer 5

find the equations of the lines


\[y-y_1=m (x-x_1) \\ \text{ where } m=\frac{y_2-y_1}{x_2-x_1} \\ \text{ so you could write this equation as } \\ y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\]

Answer 6

a system of 2 linear equations in 2-variables will never have 2 intersections:
the answer will be 0, exactly 1, or infinitely many

the answer is 0 if:
the slopes are the same but the y-intercepts are different (this is just parallel lines and parallel lines never intersect )


the answer is infinitely many if:
the slopes are the same and the y-intercepts are the same ( this just means they are the same equation and since they lay on top of each other they have infinitely many intersections)

the answer is exactly one if:
you have neither of the cases I mentioned above



so you could just find the slope and y-intercept for both lines given
and skip out on writing the equation if you want
