x is partly constant and partly varies as y.Y =2, x=30 and when y=6, x=50.(a)Find the relationship between x and y.(b)Find x when y=3

Answered by Damon
y = m x + b
2 = m (30 ) + b
6 = m (50 ) + b
-----------------------
4 = 20 m
m = (1/5)
y = x/5 + b
2 = 30/5 + b
b = - 4
so
y = x/5 - 4
x/5 = y + 4
x = 5 y + 20

now put in 3 for y
