The highest power of the variable in the polynomial is 7. Hence, the degree of the polynomial is 7.
Rearrange Line 1 and Line 3’s equations in the form of y = mx + c for easier comparison.
Lines 1 and 2 are parallel, because they have the same gradient.
Lines 1 and 3, and 2 and 3 are neither, because their gradients do not multiply to form -1.
(Gradients of perpendicular lines multiply to form -1.) c
