👉 The term "linier" refers to a mathematical function that is linear in its input. It has a slope of 0, meaning it rises and falls at the same rate from left to right or right to left. This means that for any given value of x, the output value y will also be equal to the input value x. For example, if you have a function f(x) = 3x + 2, then this function is linear because its slope (0) is
