Question

Постройте график функцииейзадоной формулой у= 3х+2 найдите графику значение у соответствии х= 1-2

Answer 1

У=3х+2;        х=1-2      х=-1    
у=3*(-1)+2        y=-1

Answer 2

Graph of the Function y = 3x + 2

To plot the graph of the function y = 3x + 2, we can use the given formula to find the corresponding value of y when x = 1 and x = -2.

When x = 1: y = 3(1) + 2 y = 3 + 2 y = 5

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

So, the points on the graph are (1, 5) and (-2, -4).

Plotting the Points on the Graph

Now, let's plot the points (1, 5) and (-2, -4) on the graph.

- The point (1, 5) represents the coordinate where x = 1 and y = 5. - The point (-2, -4) represents the coordinate where x = -2 and y = -4.

By connecting these points, we can visualize the graph of the function y = 3x + 2.

Conclusion

The graph of the function y = 3x + 2 passes through the points (1, 5) and (-2, -4). It is a straight line with a slope of 3 and y-intercept of 2.
