The constant of proportionality would be "4" ... proportional relationships are in the form of y = kx.. so in your ordered pairs, you can see that to get the 'y' coordinates you would have to multiply the 'x' coordinates by 4.
Answer:
It is A
Step-by-step explanation:
Step-by-step explanation:
numbers 1 4 and 7
We know that according to Pythagoras theorem x^2 = y^2 + z^2
64 + 225 = x^2
289 = x^2
x = 17
y = 8 = root 64
z = 15 = root 225
