Answer 3

To determine whether the given equation is a linear function, we need to check if it fits the form of a linear function, which is typically written as:

y = mx + b

where:

• y is the dependent variable (usually the output or the value we want to find).
• x is the independent variable (usually the input or the value we know).
• m is the slope of the line.
• b is the y-intercept (the value of y when x = 0).

Now, let's compare the given equation with the standard form of a linear function:

У = 7 - 9х

In this case, the equation is almost in the form of a linear function. It is linear because it has a degree of 1 (the highest power of x is 1). The only difference is that the constant term (the term without x) is 7 instead of b.

If we rewrite it as:

У = -9х + 7

Now, we can see that the equation is in the standard form of a linear function. The coefficient of x is -9, and the constant term is 7.

So, yes, the given equation У = 7 - 9х is a linear function.
