after this week, i've only got a chemistry assessment in week 10 and that's it for the term but i'll be getting a biology assessment to do over the holidays. according to my assessment schedule, term 2 won't even have half as many assessments as term 1 did. :D
x^2 = -2y
a = -1/2
focus (0,-1/2)
using two point formula with (0,-1/2) and (4,-8)
y+1/2 / x = -8+1/2 / 4
8y + 4 = -15x
y = -15x/8 - 1/2
answer above is correct. :)
