Find the value of k if it is known that the graph of y=kx goes through:

1 answer:

3 0

In y=kx , subst. -30 for x and 3 for y. Then solve the resulting equation for k:

3 = k(-30).

Dividing both sides by -30, we get:

-3/30 = -1/10 = k

The constant of proportionality is k = -1/10.

The magnitude of a vector has to do with the vector length that is used to show the initial and final position of the vector.

<h3>What is a Vector?</h3>

This refers to the quantity that has a magnitude and direction and can be used to show position.

Hence, we can see that the vector, magnitude, and the directional angle values are not given so a general overview was given.
