+5 y varies directly as x. If x = -6 then y = 10. Find y when x = 6.
Plz help i hvae a time limit on a math test
+505 Please don't cheat on your test.
I am just going to give you a few hints:
If y varies directly with x, then \(y=kx\), where k is a constant. Set x = -6 and y = -10 to solve for k:
\(10 = -6 \cdot k\\k=-\frac{5}{3}\)
Knowing what k is, plug it back to \(y=kx\), and plug 6 for x, and solve for y. You can figure this out; I believe in you!
