my teacher said its from calculus but idk how

y = -(8/6)x+8
multiply both sides by 6
6y = -8x+48
8x+6y = 48
divide both sides by 2
4x+3y = 24 (4)

wait could you explain the first step please

[obsidian needle]

(0,8) to (6,0)
m = (0-8)/(6-0) = -8/6
c = y-intercept
so +8

bro omg i got this question in my test yesterday
i was putting y=0 and x = 6 in all of them
now i realise for first two x is in the first number and the last two options have the x in the second number

i got it wrong nooooo

[ocean sinew]

so you firstly calculated the slope?

[obsidian needle]

yes

[ocean sinew]

ah i see

thank you swindle
