Answer:
y = 7.5
Step-by-step explanation:
given y is directly proportional to
then the equation relating them is
y = k
← k is the constant of proportion
to find k use the condition y = 75 , x = 100 , then
75 = k
= 10k ( divide both sides by 10 )
7.5 = k
y = 7.5
← equation of proportion

Answer:
Step-by-step explanation:
(1,9) and (-2,-2)
y2 = -2, y1 = 9, x2 = -2 and x1 = 1
m = {y2 - y1}/{x2 - x1}
m= {-2 - 9}/{-2 - 1}
m = -11/-3
m = 11/3
