Question

50 баллов!!!Постройте график уравнения 3х – у = 2.

Answer 1

По точкам 
1)у=3х-2
Если х=3, то у=7
Если х=-2, то у=-8
Получаются 2 точки: (3;7) и (-2;-8), отмечаешь их и строишь

2)Если х=3, то у=0
Если х=-2, то у=10
Получаются 2 точки: (3;0) и (-2;10), отмечаешь их и строишь

Answer 2

Plotting the Equation 3x - y = 2

To plot the equation 3x - y = 2, we need to create a graph with x and y axes and plot the points that satisfy the equation. We can do this by assigning different values to x and solving for y.

Let's start by assigning some values to x and solving for y:

When x = 0: 3(0) - y = 2 0 - y = 2 y = -2

When x = 1: 3(1) - y = 2 3 - y = 2 y = 1

When x = 2: 3(2) - y = 2 6 - y = 2 y = 4

Now we have three points: (0, -2), (1, 1), and (2, 4). We can plot these points on the graph:

(2, 4)
(1, 1)
(0, -2)

Connecting these points will give us the graph of the equation 3x - y = 2.

Graph of the Equation 3x - y = 2

Here is the graph of the equation 3x - y = 2:

     |
  4  |       o
     |
  3  |
     |
  2  |   o
     |
  1  |
     |
  0  | o
     ----------------
     0  1  2  3  4  5
            x

The points (0, -2), (1, 1), and (2, 4) are plotted on the graph, and the line connecting them represents the equation 3x - y = 2.
