The forces F1, F2, . . . , Fn acting at the same point P are said to be in equilibrium if the resultant force is zero, that is, if F1 F2 ... Fn 0. Find

(a) the resultant forces acting at P, and

(b) the additional force required (if any) for the forces to be in equilibrium.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
