Answer:
Step-by-step explanation:
Let d represent the number of days.
We have been given that a coin collector is able to collect five coins each day.
The number of coins after d days would be 5 times d.
We can represent this information in an expression as:
Therefore, the expression represents the number of coins the collector has after d days.

If order doesn't matter then the number of possible choices is:
let us take any two points here (5,20) and (7,30)
now let us use slope formula to get its slope
slope =5
now let us use one coordinate (say (5,20)) and slope to get the y intercept
20= 5*5 +b
b=-5
plugging the values of b and m in the given equation we get
y=5x-5
or c=5m-5
