Answer 1

@AlexandervonHumboldt2

Answer 2

a proportional relationship, is a mathematical relation between two variables, say \(x\), and \(y\), such that, the subsequent condition holds:
\(y=k\cdot x\), where \(k\) is any real number different from zero: \(k \neq 0\)

Answer 3

for example we can assume \(k=2\), so we get: \(y=2x\)

Answer 4

now, if I replace \(x=0\), i get:
\(y=2x=2 \cdot 0=...?\)
please continue

Answer 5

please what is \(2 \cdot 0=...?\) @jesuslover11

Answer 6

0

Answer 7

that's right! So the proportional relationship can be represented by a line which passes at point \((0,0)\), namely the origin. So, what is the right option?
