Question

является ли линейной функция,заданная формулой y=2x-3 ?как это узнать,расскажите подробно?!

Answer 1

По внешнему виду функции уже и так видно! Линейной функцией называется функция вида у=кх + в, где х входит в первой степени. У вас очевидное  уравнение линейной функции.

Answer 2

Is the function y=2x-3 a linear function?

Yes, the function y=2x-3 is a linear function. A linear function is a mathematical function that can be represented by a straight line on a graph. It has the general form of y = mx + b, where m is the slope of the line and b is the y-intercept. In the given function y=2x-3, the coefficient of x is 2, which represents the slope of the line, and the constant term -3 represents the y-intercept. Therefore, the function y=2x-3 is a linear function.
