Find the value of k if it is known that the graph of y=kk goes through A (4,-80) Please explain, I don’t get this concept and really need help!

Note: Consider the equation is instead of .

Given:

The graph of goes through A(4,-80).

To find:

The value of k.

Solution:

We have,

It is passes through the point A(4,-80). It means, the point satisfy the equation.

Putting x=4 and y=-80, we get

Divide both sides by 4.

Therefore, the value of k is -20.

idk

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
