Question

Постройте график функции у=2х-3

Answer 1

Подставляем за место X число 0. y=2*0-3=-3.Первая точка будет иметь координаты (0;-3).Подставим за место X число 1. y=2*1-3=-1.Вторая точка будет иметь координаты (1;-1).И через эти 2 точки проведи прямую

Answer 2

Graph of the Function y = 2x - 3

To graph the function y = 2x - 3, we can plot a few points and then connect them to create a line. Let's choose some values for x and calculate the corresponding y values:

When x = -1, y = 2(-1) - 3 = -2 - 3 = -5 When x = 0, y = 2(0) - 3 = 0 - 3 = -3 When x = 1, y = 2(1) - 3 = 2 - 3 = -1

Now, let's plot these points on a graph:

- Point (-1, -5) - Point (0, -3) - Point (1, -1)

We can now connect these points to create a line. The graph of the function y = 2x - 3 is a straight line that passes through these points. The line has a slope of 2, which means that for every increase of 1 in x, y increases by 2. The line intersects the y-axis at -3, which is the y-intercept.

Here is a visual representation of the graph:


Please note that the graph is a straight line with a slope of 2 and a y-intercept of -3.
