since it's the lhs we are concerned about, i. e., Y axis, so it must be either up or down. now look at the question, it says 8x2 - (1), it means one lower value of y i. e., 1 unit down

51=3k i do not get this can you help me please

lorasvet [3.4K]

51 = 3k. We can switch this around to 3k = 51 (because it's easier for me)

3k = 51.

We divide by 3 on both sides to just get "k".

3k / 3 = 51 / 3

k = 17.
