Y is directly proportional to βX
When x = 49, y = 4
(Not from the question, remember that this "When x = 49, y = 4," is to find K)
a) Find a formula for y in terms of x.
Workout:
Step 1:
Y= kβX
4= k β49
4= k (7) (Here the 7 is in multiplication, now we'll divide it meaning 4/7)
4/7= K
Step 2:
To find the formula:
y= 4/7 βX (Final relation)
Answer for a) y= 4/7 βx
