Question

______ is an equation of the form $f(x) = mx + b$, in which the variables appear only in the first degree, are multiplied by constants, and are combined only by addition and subtraction (1 point) \bigcirc function \bigcirc linear function \bigcirc term \bigcirc exponential equation

Explanation:

To solve this, we analyze each option:

• "Function" is a broad term; the given form \( f(x)=mx + b \) is a specific type.
• "Linear Function" matches the form \( f(x)=mx + b \), where \( x \) is first - degree, with constants \( m \) (slope) and \( b \) (y - intercept), and operations are addition/subtraction.
• "Term" is a part of an expression, not an equation of this form.
• "Exponential Equation" involves variables in exponents, not first - degree like \( mx + b \).

Answer:

B. Linear Function
