Which of the following are point-slope equations of the line going through (-5, 6) and (1, 1)? a. y + 6 = -6/5 (x - 5) b. y + 1 = 5/6 (x - 1) c. y - 6 = -6/5 (x + 5) d. y - 1 = -6/5 (x - 1) e. y - 1 = -5/6 (x - 1) f. y - 6 = -5/6 (x + 5)

First find the slope. 
m = (y2-y1)/(x2-x1)
m= (6-1)/(-5-1)
m = -5/6
Letter E

The lateral surface of an object is all of the sides of the object, excluding its base and top. The lateral surface area is the area of the lateral surface. This is to be distinguished from the total surface area, which is the lateral surface area together with the areas of the base and top.
