Yes, It is True first find what is a conjectures
His commission rate would be 4%
480/12000=.04
Y-y1=m(x-x1)
a point on the line is (x1,y1) and the slope is m
so
slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so
points (-2,3) and (3,0)
slope is (0-3)/(3-(-2))=-3/(3+2)=-3/5
a point is (3,0) Or (-2,3)
so it could be
y-0=-3/5(x-3) or y-3=-3/5(x-(-2)) which is equal to y-3=-3/5(x+2)
that's the answer
B is answer
Create and solve an equation of ratios:
10 ft 8 oz
------- = -------
x 48 oz (note that 3 lb = 48 oz)
Then 480 = 8x, and x = 60 ft (answer)
