Question

Сделать график y=3x по математике

Answer 1

У=3х - график прямая линия
чтобы построить прямую достаточно две точки
при х = 0  у = 3*0 = 0
       х = 1  у = 3*1 = 3

Получили две точки:  О(0;0)  и А(1;3)  Через них проводим прямую

(как получили точку А: на оси Х находим точку 1 и проводим через нее линию вертикально, потом на оси У находим точку 3 и проводим линию горизонтально.  Где пересекаются эти две линии и ставим точку А)

Answer 2

Graph of y = 3x

To create a graph of the equation y = 3x, we can plot several points and then connect them to form a straight line. The equation y = 3x represents a linear function with a slope of 3 and a y-intercept of 0.

Let's plot a few points to create the graph:

- When x = 0, y = 3(0) = 0. So we have the point (0, 0). - When x = 1, y = 3(1) = 3. So we have the point (1, 3). - When x = -1, y = 3(-1) = -3. So we have the point (-1, -3).

Now, let's plot these points on a coordinate plane and connect them to form the graph of y = 3x.


The graph of y = 3x is a straight line that passes through the points (0, 0), (1, 3), and (-1, -3). It has a positive slope of 3, which means that as x increases, y also increases. The line intersects the y-axis at the origin (0, 0).

Conclusion

The graph of the equation y = 3x is a straight line with a slope of 3 and a y-intercept of 0. It represents a linear function where y is directly proportional to x. As x increases, y also increases. The line passes through the points (0, 0), (1, 3), and (-1, -3).
