The values of x and y vary directly and one pair of values are given. write an equation that relates x and y. x=2,y=5

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.
