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

If value of cos330° is √3/2 then find tan165°.

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
