Question

Какие из точек а(-1;-2) В(4;-2) С(0,4;0) и D(10;1) принадлежат графику уравнения х:у=2х-10

Answer 1

ответ В потому что 4*2-10=-2

Answer 2

Points on the Graph of the Equation x:y=2x-10

The equation x:y=2x-10 can be rewritten as y=2x-10. To find which points among A(-1,-2), B(4,-2), C(0,4), and D(10,1) belong to the graph of this equation, we can substitute the x-coordinates of these points into the equation and check if the resulting y-coordinate matches.

- For point A(-1,-2): - Substituting x=-1 into the equation y=2x-10 gives y=2*(-1)-10, which equals -12. Therefore, point A(-1,-2) does not belong to the graph of the equation.

- For point B(4,-2): - Substituting x=4 into the equation y=2x-10 gives y=2*4-10, which equals -2. Therefore, point B(4,-2) belongs to the graph of the equation.

- For point C(0,4): - Substituting x=0 into the equation y=2x-10 gives y=2*0-10, which equals -10. Therefore, point C(0,4) does not belong to the graph of the equation.

- For point D(10,1): - Substituting x=10 into the equation y=2x-10 gives y=2*10-10, which equals 10. Therefore, point D(10,1) does not belong to the graph of the equation.

In summary, the point that belongs to the graph of the equation x:y=2x-10 is B(4,-2).
