Find the slope of a line passing through 8,-1 and 9,2

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

Asap (i need to finish this quick) graph complete the sequence of transformations that produces △x'y'z' from △xyz. a clockwise rotation ° about the origin followed by a translation units to the right and 6 units down produces δx'y'z' from δxyz.

Which ordered pair is a solution of the equation? 2x+3y=10
