In order to calculate whether the graph of the function, which is given by the equation y = -5x + 2, belongs to the point M with coordinates (-20; 102), we will start by substituting the coordinates of the point into the equation of the function and performing the actions.
If as a result we get the correct equality, then we can say that the point belongs to the graph of the function.
So, we substitute the values and get:
102 = -5 * (-20) + 2;
102 = 100 + 2;
102 = 102;
We got the right equality. So the point belongs to the graph of the function.
Answer: the point belongs to the graph.
