Convert a two-variable linear equation 0.5x + 0.25y = -2.

We transform the linear equation with two variables 0.5x + 0.25y = – 2 to the form of a linear function.

Let’s remember what a linear function looks like.

A linear function is a function of the form y = kx + b, where k and b are any numbers (they are called coefficients).

In other words, a linear function is such a dependence that the function is directly proportional to the argument.

We transfer the term with x to the right-hand side of the equation; upon transfer, we change the sign to the opposite.

0.25y = – 2 – 0.5x.

Multiplying both sides of the equation by 4, we get:

y = – 2x – 8.

Answer: y = – 2x – 8.
