I need help with these 2 problems please. and please make it legible.

The vector v = ai + bj is perpendicular to the line ax + by = c. Use this fact to nd an equation of the line through P perpendicular to v. Then draw a sketch of the line including v as a vector starting at the origin. P(-2,-9)v= -2i+j The equation of the line is |:. (Type an equation.) A force of 80 pounds on a rope is used to pull a box up a ramp inclined at 10 from the horizontal. The figure shows that the rope forms an angle of 33 with the horizontal. How much work is done pulling the 80 pounds box 28 feet along the ramp? 330 100 . . . . . The work done is foot-pounds. (Round to the nearest foot-pound.)
