Find an equation of the line perpendicular to the graph of 28x-7y=9 that passes through the point at (4,1)

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.

2/3(-6y+9x) expand each expression using the distributive property
