The equation of the straight line through....

Question

The equation of the straight line through the points (50,5500) and (100,1000) is given by:

y = __x + ___

Answer 1

slope =(1000-5500)/(100-50) = -4500/50 = -450/5 = -90

(y-1000)/(x-100) =-90

y-1000 = -90x + 9000

y =-90x +10,000

check the answer with the other point

5500 = -90(50)+10000 = -4500 +10000 = 5500
