K = 32
Because if the answer is -8, after you divide, the answer has to be 4.
4 x 8 = 32
Then run it through to make sure.
32/8 equals 4
4-12 equals -8
Negative 8 or -8 I should the answer
K = -8
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
