Question

The y-intercept of the line whose equation is 2x + 5y = 8 is
8??

Answer 1

Set x at 0.

Answer 2

y=8/5

Answer 3

no,its y=8/5

Answer 4

trivial but fun :)

\(2x + 5y = 8\); /8

\(\cfrac{2x}{8} + \cfrac{5y}{8} = \cfrac{8}{8}\); simplify

\(\cfrac{x}{4} + \cfrac{5y}{8} = 1\); just drop that "5" under

\(\cfrac{x}{4} + \cfrac{y}{8/5} = 1\); just drop that "5" under

read the intercepts from the bottoms

Answer 5

did the latex mess that up on your screen?

Answer 6

took a second or 2 to render and got "just drop that "5" under" twice, but it's fine.

Answer 7
