Answer:
Step-by-step explanation:
An expression means that we don't know enough to create an equation. So, this means we will mostly be using variables.
John runs r amount every day. We need to create an expression for if he runs r amount for 4 days.
r = how much he runs per day
4 = how many days he runs
z = how much he runs this week
This is your expression!

18 divided by 2 = 9
7/9 is the same as 7 divided by 9
= 0.778
I'm going to go right ahead and assume that we're talking about a linear equation.
The linear equation passing through the points given is y=3x+4, since it satisfies both of the points given.
