Does the graph of the function y = -2x + 4 pass through point C (20; -36).

In order to find out if the graph of some function passes through a point with coordinates (x, y), it is necessary to substitute x and y into the linear function of this graph, if the equality is true, then the graph passes through the point, if the equality is not true – the graph through the point does not pass.


-36 = -2 * 20 + 4

-36 = -40 + 4

-36 = -36

Conclusion: The graph passes through a given point
