What is the formula for directly proportionate?

  y = kx

Step-by-step explanation:

Y is directly proportional to x if the relation can be written using the equation ...

  y = kx . . . . . for some constant k

__

Note that k may be positive or negative. The graph of this equation is a straight line through the origin.

The value of k can be found from corresponding values of x and y using ...

  k = y/x

This is also another way to express the fact that x and y are proportional.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
